The Roosevelt elk of Western WA tend to have smaller racks & bigger bodies than the usual Rocky Mountain elk. This cartridge was able to match and even excel in several ballistic categories compared to the .30-06, one of the most popular long range, big game cartridges at the time, but the 7mm rem came with much more tolerable recoil when compared to other magnum cartridges on the market. The .300 Win Mag rounds show a slightly higher sectional density than the 7mm Rem Mag rounds. Complete 7mm Remington Magnum Winchester ammunition ballistics Chart. Why 7mm Rem Mag over the new 7mm WSM? 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. Let’s continue and see what we find. From this graph, it is easy to see that these two cartridges show very similar trajectories out to 500 yards. BONUS OFFER: Get your 500 Page Ammo Comparison Handbook (worth $43) for FREE right into your inbox. 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. Regardless, if I had to pick just one of these for all-round hunting, it would be the 7mm Rem. Comparing the .270 with the 7mm Remington magnum is like comparing grits and white cornmeal. Parent Case: .375 H&H Magnum 2. Some of these factors include the velocity, the caliber of the bullet, the weight of the bullet, and the bullet’s design. vs. 7mm Rem. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, 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. If you are planning to shoot factory ammunition only, check back here for Part Two of this cartridge comparison blog. 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. Just as with the smaller set of rounds we just looked at, these two cartridges are nearly identical in their trajectories. 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. The higher B.C. We have compiled the velocities of the ten selected rounds from the manufacturer’s websites and have listed them here. What is interesting is that as these rounds move downrange, the gap between the two cartridges begins to close. Let’s take a look at the bullet energies ( of the ten selected rounds from the muzzle out to 500 yards (Graph 7). If you need a round that’s going to resist wind deflection and drag, both the 7mm RM and the .300 WM have options to get the job done. entsprechend lange/schwere bleifreie), so kann es sein, daß diese nicht mehr präzise fliegen. More expansion causes a larger wound and also transfers the energy carried by the bullet more efficiently. 7mm Magnum Showdown: 7mm Rem. 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. The higher the sectional density, the less resistance the bullet encounters because of the smaller area that is interacting with the target. The top two performing rounds are a 7mm Rem Mag and a .300 Win Mag option, and they only have a difference of .6″. The 7mm (.284-inch) bullet drops less at all ranges even though the .308-inch bullet has a more efficient, minimum drag B.C. Mag. We are interested in how long these rounds can maintain supersonic flight because it influences the calculations you will have to make to be accurate with long range shots. 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. At the 300 yard mark, we are looking at insignificant differences between the two cartridges. You might have more options for flat shooting rounds for the 7mm RM but be aware that there are .300 WM rounds that can easily compete for flat trajectory. And like we have mentioned before, using a proper bullet and putting it in the right spot can make up for lack of energy. In the table below I used the term "mid-range trajectory," abbreviated "MRT." Because we are looking at factory loads, we were very conservative with the amount of powder as factory loads are often loaded with grain in far less amount than the max capacity. This way, you can have more data at your disposal if you are looking to make a decision, and it will also check our small sample group and help us confirm that the results we are seeing is accurate for the cartridges as a whole. We do know what there is a lot of range in the limits for both cartridges. Let’s take a look at the averages of the full data sets. Though there is a slight difference in the averages, we don’t think it is a fair way to decide which of the cartridges have the better ballistic coefficients. With these two cartridges, we see fairly similar limits for supersonic flight though the 7mm RM rounds have, on average, 36 more yards of supersonic speed. You can definitely save a few cents per round by looking into handloading for both of these cartridges. 300 Remington Ultra Magnum Load Data; 7.62x51mm NATO Load Data; 8x57mm JS Mauser Load Data; 8mm-06 Load Data; 325 Winchester Short Magnum (WSM) Load Data; 8mm Remington Magnum Load Data ; 338 Federal Load Data; 338-06 A-Square Load Data; 338 Winchester Magnum Load Data; 330 Dakota Load Data; 340 Weatherby Magnum Load Data; 338 Remington Ultra Magnum Load Data; 338 Lapua Magnum … In the simplest explanation possible, the ballistic coefficient gives you an idea of how well a bullet is streamlined and how well it can overcome air resistance. In 2004 I took my 99 .270 WSM and a light .375 H&H. I went back to the .308 until I went to Africa again in late 90s and then 2004. in 99 I took a .300 Weatherby and a .375 Weatherby. The cartridge is also able to be to take a variety of bullet weights. 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. In this next section, we are going to look at several sub-categories of stopping power. We are not here to lobby for one cartridge over the other. Rifling Twist: 1:9 to 1:10 3. For the sake of clarity and brevity, we decided on only five selections each. With practice, either one can easily become your go to round. 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. 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. The following ammunition cartridge ballistics information and chart can be used to approximately compare .270 WSM Winchester Short Magnum vs .300 Winchester Magnum ammo rounds. We will look at several ballistic categories as well as other performance specs throughout the article, and we hope that in the end, you come away with information for a more educated decision based on your hunting and shooting needs. There are 7mm Rm rounds that outperform some .300 Win Mag and vice versa. We have listed the average cutoff for supersonic flight in the table below. The higher the momentum, the more the bullet can penetrate after encountering resistance. If you are wanting a BC in the .05+ range, there are options for that with both of these cartridges. 3.5 lbs. A war’s been raging since 1963. The following ammunition cartridge ballistics information and chart can be used to approximately compare .300 WSM Winchester Short Magnum vs 7mm-08 Remington ammo rounds. Mag. 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. 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. 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. Let’s run a quick ballistic comparison and see the tale of the tape. And what shouldn’t be lost, is that while the .300 Win Mag does seem to have more KE, the amount that the 7mm RM rounds generate are not insignificant. Both cartridges fit through standard length actions, both maximize performance in 26-inch barrels but do fine in more convenient 24-inch tubes. The physics and math behind the ballistic coefficient and its implications, while interesting, is not something we are going to attempt to convey in this article, but we do urge you to check it out. 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. We have calculated the sectional densities for all ten of the selected rounds have compiled them here (Graph 8). A war’s been raging since 1963. A maximum bullet rise of 1.5 inches is appropriate for shooting small animals, as they present a small target, particularly if head shots are necessary. We are looking at the bullet drop (inches) from the 50 to 300 yards with the firearm zeroed in at 100 yards. Most brands offer 170 to 175-grain options in 7mm RM. We have to cut it off somewhere. With two decades of chasing all manner of upland game, hooved mammals, strutting gobblers, and any small game that can fit in his Dutch oven, he hopes to offer new ideas and viewpoints on hunting and firearm concepts and traditions. Even so, it’s really more about picking the correct round rather than the correct cartridge. Just like with the 7mm WSM vs 7mm Rem Mag and 300 WSM vs 300 Win Mag, even though the 325 WSM uses a case with a larger diameter, the .338 Win Mag itself has a relatively large diameter case and is significantly longer. 14.07 fps                              24.6 foot-pounds, 300 Win. The heavier, larger caliber bullet delivers more energy at all ranges despite starting with a slower MV. The .300 Win Mag is not only a hunting caliber but is also favored by long range competitive shooters. G1 Ballistic Coefficient Must be between 0.001 and 1.0. It's not because of the cartridge. Both the 7mm Rem Mag and the .300 Win Mag were designed from the same parent casing, but their final dimensions do have some very significant differences. The recoil energy for these rounds was generated as we described earlier and used the same variables. That changes the ballistics significantly in favor of the 7mm and might alter your plans. We don’t think there is any difference in availability between the two, though there is less compared to other popular hunting rounds. The 7mm Rem Mag rounds have a slightly flatter trajectory, on average, and this is most pronounced at 700+ yards, but when looking at individual rounds, there is a mixture of both cartridges from the high end of the bullet drop range to the flattest shooting rounds. And if you need some extra power at short range the differences are nowhere enough to make you decide against the .300 Win Mag. However, the.300 Winchester Magnum generally uses heavier bullets than the 7mm Remington Magnum. Those are always the deciding factors: right bullet, right place. By doing this, you as a reader has a better resource and source of knowledge to make your own decision. Handgun Back. 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. Though the averages give a slight advantage to the 7mm Rem Mag in flat trajectories, especially as it moves out to the 600 and 700 yards range, the two top performing rounds at each yardage marker was a 7mm RM and a .300 WM. Both are excellent cartridges. Contrary to popular belief, the heavier bullet does not drift less in the wind. Though the 7mm Rem Mag rounds are a smaller caliber than the .300 Win Mag rounds, they also have lighter bullets. With the larger sample size, we see the same trend that we saw above. Size matters, so let’s stick to the two older magnums. vs. .300 Win. The 300 WSM will have more recoil than you presently have, but put on a Vais muzzle brake and recoil will … 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. Let’s take a look at the larger sample set and see how the two compare. So when you look at the SDs of various cartridges and specific rounds, higher SDs correlate to deeper penetrating bullets. Lbs.) Mag. As well as our in-depth look at the 7mm Remmington Magnum. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. In the larger data set, the .300 Win Mag had a .006 advantage over the 7mm RM rounds. Both of these cartridges sports rounds with ballistic coefficients well over .45 and each have rounds with BCs above the .6 mark. Right from the muzzle, the lowest .300 Win Mag round is carrying 3, of force while the highest 7mm Rem Mag round is carrying 3, of force. Wind deflection is determined by a combination of B.C. In our opinion, you can become accustomed to any recoil within reason it still stands that certain amounts can cause you to flinch or close your eyes before a shot. Velocity is also a key component in a bullet’s ability to expand, but for now, we are just going to stick with comparing the energies of the rounds involved. Weight is only a part of B.C. 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. You really are comparing apples and oranges. 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. The 7mm RM has a flatter trajectory throughout the bullet’s range, but the largest difference seen between the two cartridges is only 0.9 inches at the 400 yard mark. In fact, the flattest shooting and steepest dropping round are both 7mm Rem Mag rounds. Well, I wouldn’t be. 15.64 fps                             30.4 foot-pounds. In a nutshell, here’s why: given equal rifle mass, optimum bullet Ballistic Coefficients and Muzzle Velocities in each caliber, the 7mm RM will shoot flatter, drift less and recoil with less brain jarring recoil than the 300 WM. 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. This is more than enough velocity to get proper terminal ballistics for these rounds but keep in mind some of these are not intended for hunting purposes. Both cartridges have their rounds with heavier bullets and subsequent higher SDs. 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. 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. 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. You might see slower velocities as well as changes in bullet energy and trajectory. Not only are you taking into account elevation but wind as well. It is important to make clear that we are looking at recoil energy and not the actual kick or felt recoil, though increased recoil energy for one round over another will often translate to increased felt recoil of the same round. Firearm Setup. For the 7mm Rem Mag rounds, we are big fans of the HSM Trophy Gold VLD Berger 168gr round. Neck: 8.6mm 5. Both of these combined, barring bullet design, indicate that the .300 Win Mag should have better penetration potential. The old 7mm Rem. It will a produce a line graph showing the bullet drop and flight path of the bullet. Bullet: 7.8 mm 4. Most brands offer 170 to 175-grain options in 7mm RM. Higher BC rounds tend to have flatter trajectories. Survival. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. And we are sure its performance also had something to do with its decades of success. As the species increase in size so does the amount of energy. Survival. The .100″ bullet is going to have a larger SD than the .200″ bullet and theoretically, deeper penetration. While hand loading and the art of balancing the various components that go into a cartridge is a topic worth discussing, it is beyond the scope of this article. This is because the MV was 200 fps faster. Receive our newsletter with the best articles covering guides, guns & gear. For us and the majority of hunters we know, putting down an animal quickly and humanely is of utmost importance. Because of this, we can easily compare two cartridges rather than having to look at the individual bullet types used. Let’s take a look at the how the recoil energy between these two cartridges compare when we work with a larger data set. It has one the best muzzle velocities and BCs of all the rounds we looked at so you have excellent downrange ballistics, including a flat trajectory. 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. (Or read, 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. If we do go by this rule, the 7mm Rem Mag rounds still could be troublesome for some hunters and marksmen though still a good bit lighter than the .300 Win Mag rounds. We are again seeing that both of these cartridges are performing very similarly. Given that the mass and velocity make up bullet momentum and since there was very little difference in velocity between the cartridges and the .300 WM rounds have heavier bullets, it makes sense that they generate more momentum.
