The 7mm Rem Mag rounds have more options for higher muzzle velocities, flatter trajectories, and better BCs which helps performance greatly downrange. Let’s see if the trends continue in the same direction when we look at more rounds for both cartridges. You can cherry pick a round from each and see quite a bit of difference as we did earlier, but there are a lot that carries very similar energies, and we saw that as they travel downrange they even out even more. We don’t think there is any difference in availability between the two, though there is less compared to other popular hunting rounds. It influences recoil, trajectory, and it even influences stopping power of the bullet in several different ways. Even so, it’s really more about picking the correct round rather than the correct cartridge. Again, with the larger set of rounds, we see the sameresults from earlier. Truly appreciate you watching the videos! This cartridge can be packed with large amounts of powder giving it a huge advantage in velocity and the ability to carry a large amount of energy over a greater distance. The 300 on the other hand will do 1583 feet/sec, have 1002 ft/lb remaining and drop 290 inches. Mag. IF you put either of them in the vital zone, they are both going drop the animal. Mag and 7MM. The sectional density correlates with the amount of penetration a bullet will have on the target, and since we are not looking at bullet types and designs in this article, we think the SD is a good means of comparison for two cartridges. With that, we feel it’s important to look at the short range trajectories (Graph 5). The 300 Win. With comparable bullet weights, the 7mm Mag. When you know when these effects start occurring, you can adjust accordingly or go with a round that might give you more flight time at these speeds. is a hard hitting and accurate cartridge, offering a 150 fps velocity increase over the .30-06 Springfield. It might be a bit of overkill for medium sized game and you might get a bit more damaged meat, but there is little doubt that it will put them down. With two cartridges that have the potential and the reputation for long range shooting, we wanted to also look at how long these cartridges can stay in supersonic flight. It’s all nitpicking to us. But, for me personally, I smile every time I reach for the .300 Winchester Magnum. And, like the smaller sample set that we just looked at in our graph, the difference between the two cartridge’s average is less than 100fps at each yard marker. The 7mm Rem Mag had on average slightly higher BCs and slightly flatter trajectories out past 500 yards than the .300 WM rounds, but as we stated during those discussions, there are rounds for both that perform better than others. In the larger data set, the .300 Win Mag had a .006 advantage over the 7mm RM rounds. The velocities produced were understandably lower than those of the 7mm Remington Magnum—as the powders available in 1912 certainly weren’t the same as those in 1962—but the cartridges are nearly identical, with the H&H design having a bit more taper. Ditto the.300 Win. Even without the highest performing round, we still see the rounds from each cartridge grouping together pretty tightly. The .300 Win is a good cartridge. This speed along with the sectional density is going to be more than enough to penetrate to and through vital organs of big bull elk and moose at long ranges. Both cartridges also have heavy enough bullets and the terminal ballistics to be used for larger game such as elk, moose, and more exotic game and still have a wide effective range. We know from basic physics that if the cartridge can be fitted with larger and heavier bullets and sent downrange at increased speeds (more powder) than they should carry extra force with them. I have taken everything from elk to deer to antelope with it. Both are celebrated by hunters worldwide, but which one of these classic .30-caliber cartridges will come out on top My opinion is that the choice may heavily depend on what game animals you intend to hunt, allowing the bullet weights available dictate the logical choice. The .300 WM rounds are generating more momentum from the muzzle out to 500 yards. And we’re not discounting that method, it can be very valuable, but you just have to be cautious of who you are getting that information from. While both of these rounds can function in long range precision shooting, the majority of users are going to be using them in a hunting capacity. Best Concealed Carry Insurance [Comparison Chart], If you’re looking at a cartridge comparison, you are going to end up looking at the ballistic categories. And with the internet at your disposal, finding exactly what you need has never been easier. has an obvious weight advantage, topping out at 240 grains. Penetration is another component to a bullet’s stopping power that we want to address in this article. 7mm Remington Magnum A stellar choice for many reasons. Right from the muzzle, the lowest .300 Win Mag round is carrying 3,474ft.lb of force while the highest 7mm Rem Mag round is carrying 3,303ft.lb of force. For two cartridges that overlap in so many applications, it is easy to get on the path of trying to determine which cartridge is better. 7mm Rem. And recoil does play a role in choosing a cartridge, especially if you are dealing with a decision on cartridges that can be used for similar applications. Because of this, we can easily compare two cartridges rather than having to look at the individual bullet types used.

Updated August 2018.The 7mm Practical is a cartridge of my own design. Stopping power is extremely important in a hunter’s decision for a cartridge. While we will not be graphing all of these rounds (that would be a nightmare for your eyes) we have calculated averages for both and will present those at the end of each section. Virtually every one of our bullet diameters have received the magnum treatment at one point in time or another, be it from the Weatherby family of cartridges, or the dynamic duo of Winchester and Remington, or even the boutique shops like Lazzeroni. By Chuck Hawks. by Philip Massaro - All five of the .300 Win Mag rounds produced between 27 and 32ft.lb of energy, between 7 and 14 more ft.lb of recoil energy than the 7mm Rem Mag rounds. If you want a flat shooting round for short hunting situations, both the 7mm RM and the .300 WM are going to get the job done. Ron Spomer has worked extensively with the 7mm Rem. In this cartridge comparison of the 7mm Rem Mag vs .300 Win Mag, we are dealing with two cartridges that each carry loyal users and often find themselves the subject of heated debate on numerous firearm forums and within hunting lodges. THE BEST GUN DEALS AND HANDPICKED GEAR RECOMMENDATIONS, Subscribe to our Newsletter and we send you the best deals right into your inbox. A 175-grain or 180-grain in the 7mm Rem. So when you look at the SDs of various cartridges and specific rounds, higher SDs correlate to deeper penetrating bullets. Let’s take a look at the averages of the full data sets. (Graph 4). We do see that the Barnes .300 WM round is a big boost to the averages and without it, the average performance between these cartridges would be much similar. Mag. Heck, one person’s results can be different from day to day. For the .300 Win Mag rounds, all of the them leave the muzzle with over 75lb/ft.s of momentum while all of the 7mm RM rounds are below the 70lb/ft.s mark. Below you can find some very, very brief histories of these two cartridges. It does give you a better idea of which cartridge has more options for higher performance numbers for each specific category. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. We are looking at the bullet drop (inches) from the 50 to 300 yards with the firearm zeroed in at 100 yards. It gave velocities previously unattainable—at least from an American cartridge—in the 7mm bore diameter, and the new rifle certainly didn’t hurt the popularity. When the powder in the casing is ignited, and the bullet is forced down the barrel and down range, that energy created from the burning powder is carried by the bullet. From this graph, it is easy to see that these two cartridges show very similar trajectories out to 500 yards. Cinder blocks with these two power houses!!! In the grand scheme of things, we don’t know if that is enough to sway you towards one cartridge or the other without taking into consideration other performance specs. The .300 Win Mag came into production by Winchester in 1963. If you’re a hunter, competitor, or just enjoy shooting, understanding how your cartridge of choice behaves in flight and understanding its limitations is critical to your level of success. Both of these cartridges sports rounds with ballistic coefficients well over .45 and each have rounds with BCs above the .6 mark. While there are general rules of thumb for what is required, nothing is set in stone, and as we just mentioned, there is more involved than just bullet energies. will supersede the velocities of the .30-06 Springfield; though the ’06 can use heavier bullets, the 7mm of equal weight will offer a better Sectional Density. Both camps have fervent followers, and both are highly effective in the game fields. Most weights are within the 150-200 grain range, but there are several lighter and heavier rounds available. Stopping or knockdown power as some like to call it is going to be more important to those looking to utilize these cartridges for hunting purposes. After we have examined these sections, we should have a much clearer understanding of where these cartridges excel and where they fall short and will let us begin teasing apart applications one cartridge might be favored over the other. Given that the cartridge is still around tells you that it is able to bring down large game efficiently. But I am really curious about what your thoughts are on the 7mm-300 WM vs. the 338 Lapua Mag on the effective external and internal ballistics for hard target interditions out to 1500m+ on these two rifles. It is also not uncommon to see slightly different performance firing these rounds from your rifle compared to computer generated data. It’s been all over with me on hunting trips, including Africa, Canada and here at home. Mag. Both are relatively easy to handload for those who head down that road, running on a good slow-burning powder and a large rifle magnum primer, and both exhibit excellent accuracy with both factory and handloaded ammunition. Both cartridges were released to the public hardly a year apart and further adds to the rivalry that has been raging. 270 vs 30-06 Debate Settled Once And For All Trying to determine which cartridge is more accurate is always a task that makes us feel a little dirty. For the .300 Win Mag, our choice goes to the Nosler Trophy Grade AccuBond Long Range 190gr. BONUS OFFER: Get your 500 Page Ammo Comparison Handbook (worth $43) for FREE right into your inbox. Remington’s 7mm Mag. The majority of bullet weights used for the 7mm rem mag rounds for hunting purposes fall between 150 and 180gr though there are outliers of lighter and heavier bullets. Before we wrap up this article, we want to take the ten rounds we have been looking at and pick a couple that we think fits certain applications well. Even with today’s rifle optics, you can ask anyone whether adjusting for a 45″ drop or a 65″ drop is easier and 45″ will be the answer every time. This difference between the two leads us to rounds that have very similar SDs. The case and overall length of the .300 Win Mag are slightly longer than the 7mm RM, and its overall case capacity has a larger volume. The averages definitely lean towards the .300 WM rounds for higher momentum. It betters the velocities of the .300 H&H Magnum; though it falls short of the performance of the .300 Weatherby Magnum, the Winchester variety can be housed in the standard long-action receiver, which is lighter and less expensive to produce. It was released to the civilian market in 1962 and quickly gained popularity in the hunting world. We do know what there is a lot of range in the limits for both cartridges. Ballistics comparison video between the 7mm Remington Magnum vs the 300 Winchester Magnum. To some these numbers aren’t going have any sway in their decision. While this is fine for comparing specific rounds, it doesn’t mean that the numbers are set in stone. If you are wanting a BC in the .05+ range, there are options for that with both of these cartridges. At the 300 yard mark, we are looking at insignificant differences between the two cartridges. We have listed the average cutoff for supersonic flight in the table below. We have to cut it off somewhere. As the names imply, the.300 Win Mag takes a 30-cal (.308″) bullet, while the 7mm Rem Mag takes a smaller caliber (.284″) bullet. We are again seeing that both of these cartridges are performing very similarly. Both rifles work equally as well. Just as with the smaller set of rounds we just looked at, these two cartridges are nearly identical in their trajectories. It also means that if you look around at handloading website, you are going to see numbers that sometimes vastly outperform the rounds we will be looking at in this article. Mag. gives an advantage in bullet weight. The .300 Win Mag rounds show a slightly higher sectional density than the 7mm Rem Mag rounds. And we can’t rule out the fact that we could change the bullet weights of these two rounds and close or widen the gap. As an example, let’s take two rounds, both are 100gr, but one has a diameter of .100″ and the second has a diameter of .200″. In this section, we will take a look at several ballistic categories including the velocity, the ballistic coefficient, as well as the short and long range trajectory of the 7mm Rem Mag vs .300 Win Mag. I have found the recoil between the two to be very similar, with rifle weight playing a larger part than the cartridge does. And why wouldn’t it? Receive our newsletter with the best articles covering guides, guns & gear. The 7mm Remington Magnum was the first on the scene, released in 1962 in conjunction with the new Model 700 rifle. You will find these tables at the end of each section throughout the article. Mag. As we move out to more distant markers, we start to see more of an advantage for the 7mm RM though it is still fairly close, and there are several .300 Win Mag rounds that shoot as flat or flatter than several 7mm RM rounds. I currently have both a 700 Remington and a M77 Ruger type rifles. If the round is not paired with the correct twist rate of the barrel, the bullet can be highly unstable in flight and become highly inaccurate. We have also included an additional 400 yard marker as there are certain hunting situations where this range can be a normal shooting distance. The post-World War II era saw a return to the hunting fields, and a wave of cartridge development followed, with Winchester releasing the .264, .338 and .458 Winchester Magnums in the 1950s, all based on the belted Holland & Holland case shortened and blown out. We think that most of you here reading this article would easily adjust to the increased recoil of the .300 Win Mag, but there might be some who could easily be thrown off by the kick. And when we say spread out we are still looking at a range of less than 2.5”. It's everything from a Varmint Blaster to an Elk Taker, and several other things in between. 174 Views Share Embed Download In General. ; 7mm Ultra Mag. vs. .300 Ultra Mag. Comparing the two, the .300 Win. Quite a few factors can influence the recoil such as bullet weight, the amount of powder, as well as the firearm weight. Norma followed suit, releasing their .308 Norma Magnum in 1960, giving the same ballistics as the longer .300 H&H Magnum, in a long-action cartridge. Though, for hunting purposes, just about all of the rounds for these two cartridges are going to be designed to hold together well and over controlled expansion. Winchester’s marketing—and the availability of both rifles and ammunition—saw the rapid rise to success of the .300 Winchester. No surprise there, as both the 7mm and .308″ bore diameters have long been heralded as the two most versatile available, giving hunters all sorts of flexibility regarding the game animals they will handle. What we are saying is that the differences in performance shown here will translate to differences in performance for you when using the same firearms chambered for each cartridge, so the comparisons made here are still valid. The recoil energy for these rounds was generated as we described earlier and used the same variables. Like most ballistic and other performance specs we have looked at between the 7mm Rem Mag vs .300 Win Mag, there is not a whole lot of difference between the two cartridges. We did see slightly higher sectional density numbers, on average for the .300 Win Mag and pretty significant differences in the momentum data with the edge going to the .300 Win Mag as well. As the species increase in size so does the amount of energy. As far as availability goes, just about every major ammunition company are loading .300 Win Mag and 7mm RM cartridges and most of them carry several different models of each. It is also available in a wide array of bullet styles which gives it a lot of versatility. The first thing that jumped out at us as we looked at this data is that unlike the recoil, there is not a cartridge that has an overall greater amount of velocity. I’ve used it with lead-free 150-grain bullets for African plains game, 180-grain bullets for a good number of species and 220-grain round nose bullets for bear and deer. The higher the sectional density, the less resistance the bullet encounters because of the smaller area that is interacting with the target. Before we list some these differences between the averages of the two cartridges, it’s important to keep in mind the applications you plan to use one or both cartridges for. Again, this is all relative and depends on who is holding the gun. unseated the .264 Winchester Magnum rather quickly, becoming the darling of Western hunters. We do see the difference shrink by a few lbs/ft.s but overall, the .300 Win Mag seems to have the advantage if you are wanting more momentum. The .30/06 vs. the .300 Winchester Magnum. If you look around the internet long, you will find that there are circles of devout followers and also unbelievers in the .300 Win Mag for various reasons. When we look at the price of the 7mm Rem Mag vs .300 Win Mag, it can vary from round to round. While this cartridge has been and is still used in sharp shooting corners of the military, the majority of its action is found in the hunting world. For long range precision shooting, both of these rounds have options to get the job done. In the table below, we have listed the average bullet drop for the two cartridges below. Because of this, it will be interesting to see how these two cartridges stack up in various performance categories. The second metric that we will use to get an idea of how these two cartridges compare in potential penetration is the momentum of the bullets. We think the 168gr bullet is a great weight for hunting purposes as it has a manageable recoil. I’ve found that the versatility of bullet choice gives the .30s an advantage—if you appreciate the “one-gun” approach. To engage this 7mm RM vs. 300 WM argument you have to be willing to pick at nits because, bottom line, both cartridges (and many other magnums like them) are winners. You see, just as the famous .375 H&H Magnum came onto the scene, Holland & Holland released the .275 H&H Magnum, with a 2.50″ case and the H&H Belt. Moment is simply how well an object in motion will stay in motion. We think which cartridge has the better accuracy comes down to the person pulling the trigger and their level of experience shooting said cartridge. Look on any forum discussing shooting and the ballistics of a certain cartridge, and you are bound to see the topic of trajectories pop up. While both of these cartridges were designed with longer range capabilities in mind, they are both also hunting rounds, and with hunting, you are going to come across as much or more shots at targets within 300 yards depending on the terrain and the game. There are 7mm Rm rounds that outperform some .300 Win Mag and vice versa. Comparing the two, the.300 Win. Yet, it bridges the gap between the favorite .30-calibers of .30-06 and .300 Win.Mag… makes for an impressive elk, moose, and bear rifle. vs. .30-06; 7mm STW vs. .300 Wby. Just between cartridges, we don’t think there is enough of a difference to choose one over the other based on price. Below, you will find the numbers for the larger data set. The .270 Winchester vs. the 7mm Remington Magnum. At these normal hunting ranges, you are not going to get an advantage by going with one cartridge over the other. Higher BC rounds tend to have flatter trajectories. The amount of energy that is required to bring down game varies from animal to animal. The difference between the highest .300 Win Mag and the lowest 7mm Rem Mag round is even more drastic with a difference of 615ft.lb of force. Here are the differences in averages of the 7mm Rem Mag vs .300 Win Mag; 300yds (.34”), 400yds (1.32”), 500yds (2.62”), 600yds (3.08”), and 700yds (6.96”). It is versitile, flat shooting, has reasonable recoil, and with the effeciency of its projectiles, offers downrange energy rivaling many of the .300 Win loads. Below we have listed our ten selections to be used in this article. The 7mm Remington Magnum drives the wide variety of 7mm bullets, from 120 to 175 grains, at respectable velocities. I always bring my 300 win mag as a back up incase my 06 scope gets bumped or for a really windy day, but my 06 is the go to rifle. In this next section, we are going to look at several sub-categories of stopping power. While we will examine it as a standalone performance category, velocity has its hand in just about all other performance specs of a cartridge. Instead, we want to present the numbers and discuss any strengths and weakness of both cartridges. Moreover, its.156-inch shoulder sits further forward than the 7mm Rem Mag shoulder. Winner:.300 Win Mag has an obvious weight advantage, topping out at 240 grains. If we were to take averages of all the rounds, then there would be a slight advantage to for the 7mm Rem Mag rounds at each yard marker and each time the difference is less than 100fps. As we start top close out this comparison, let’s try to take the results we have found and start teasing apart certain applications of these cartridges might be better suited or maybe applications where you can’t go wrong with either. And that is not to say that the 7mm RM rounds are not going to penetrate well. In this case, the 7mm Rem Mag shows slightly less bullet drop than the .300 Win Mag round and even at their most distinguishable range, we are only looking at around 5” difference. Rem. In this section, we are going to look at the sectional density (SD), which is a number calculated from the caliber of the bullet, as well as its weight. Let’s take a look at the larger sample set and see how the two compare.
