The .300 Win Mag Nosler Trophy Grade, AccuBond Long Range 190gr round, stands out to use from a hunting perspective. Where ballistic calculators are used we kept as many variables the same between rounds of the same cartridge. Mag. From the muzzle out to 200 yards, the .300 WMS has a slight advantage when looking at the averages though the difference is less than 100fps. As we have seen with most of the other categories, there is a lot of similarity between these two cartridges. So, the .300 Win Mag is slightly more powerful, has a slightly flatter trajectory, and has somewhat more recoil than the .30-06. Looking only at the averages, the .300 WM hold around a 50-100ft.lb advantage over the .300 WSM from the muzzle out to 500 yards. Rifles chambered for the .300 WSM are lighter than rifles chambered for the .300 Win Mag and this reduction in weight often means a bit meaner kick. If you look individually, there are better performing rounds for both cartridges. If you’re to shoot at … And there are some differences in the cartridge specs as well as the types and weights of bullets more often used for each cartridge. 300 Ultra Mag vs 300 Win Mag. It’s not that you can’t get what you want of the .300 WSM, but you might have to shop around more for it. It’s still relative though, and might not make much of a difference to a lot of you reading this. It doesn’t have the highest BC compared to the other rounds, but it is still fairly high, and users seem to be very happy with its performance at long ranges. The majority of the data is available from the manufacturer, and where that was not available, we relied on ballistic calculators from trusted sources. 300 Win Mag vs 30-06 . The increase in length of the .300 WM over the .300 WSM is greater than the increased wideness of the case of the .300 WSM. For more detailed ballistics information please refer to the exact round in question or contact the manufacturer for the pertinent information. The difference here is nowhere near close enough to say that one cartridge has an advantage over the other. It does appear that in our selection, there are several more rounds of the .300 WM that have bullet weights in the 190+ bullet weight category than the .300 WSM rounds. Most hunters/marksmen want a flat shooting round. If you were to take the price of every round for each cartridge and average it, the .300 Win Mag might be a couple dollars more expensive, but most people are going to be more concerned with the performance of the round. All of these categories including the categories outside of ballistics all go hand in hand and influence each other. From the muzzle out to 200 yards, all of the rounds group pretty tightly together but we do see the two .300 Win Mag rounds show slightly higher energy than the other eight rounds. Some argue that kinetic energy is the most important, some argue for momentum, and some argue that neither give you useful information. It bettered the velocity of the benchmark .30-06 Springfield by over 200 fps, yet could fit in a standard long action. It is probably a bigger factor in selecting between one over the other for younger or inexperienced shooters. The .300 WSM rounds are not too far off staying in the range of 24 to 26ft.lb range. One aspect that has changed by adding the extra rounds is that the .300 WSM seems to keep its slight advantage over the .300 WM rounds out past the 200 yard mark. While the .300 WSM has a slightly longer supersonic flight than the .300 WM, on average, it is only by thirty yards. We compiled the energy data from the manufacturers of these ten rounds and graphed them below (Graph 7). Mag., it … Understanding this allows you to take the necessary steps when calculating shot placement. As far as an advantage for one cartridge over the other, there is never more than an inch of difference between the averages of the two cartridges at any point over the bullet’s range. Both of these cartridges have rounds that leave the muzzle in the 70-80lb/f.s range with the .300 Win Mag rounds having a slight advantage when looking at the averages. Again, the above is for comparative information purposes only, and you should consult the exact ballistics for the particular .300 Weatherby Magnum or .300 WSM Winchester Short Magnum cartridge you're looking at purchasing. In the table below, we have listed the average bullet momentum numbers over a 500-yard range for the forty compiled rounds. We have a variety of deals on Rifle Ammo, Handgun Ammo, Shotgun Ammo & Rimfire Ammo, as well as ammo for target practice, plinking, hunting, or shooting competitions. As well as our in-depth look at the 7mm Remmington Magnum. While both cartridges use .308” bullets, the .300 Win Mag usually is loaded with heavier bullets than the .300 WSM. With that, there were several .300 WSM rounds with BCs from .5 to over .6. In our opinion, both sides of the 7mm Rem Mag vs. 300 Win Mag fence offers comfortable, efficient ‘seating’! If you are on the range, we like the .300 WSM Barnes VOR-TX TTSX 165gr round. This cartridge is easily one of the most, if not the most, popular magnum cartridges in the world when it comes to factory loads. can, and does, take a 165-grain bullet and push it more than 550 fps faster than the .300 Savage—a short-action cartridge old enough to be going through a mid-life crisis when the Winchester .30-caliber magnum was born. All of the ten rounds are interspersed in the graph which means each cartridge has the options for faster and slower rounds. Though, we do see a little bit more of a distinction between the averages of the two cartridges. For hunting large game, you would want more momentum to be able to push through thicker hide and bones which are denser and provide more resistance. When it comes to this type of data, there is no concern with comparing cartridges, but you should be aware that these numbers can change when being fired from your rifle. It’s always good to look into the similarities and differences of two cartridges, but at times, your decision really should be made based on other factors. We examine the history of these cartridges and compare them side-by-side in several categories that are important to hunters and sport shooters. Both rounds produce a significant amount of recoil energy and you might see that difference shrink even more if the .300 WSM rounds were to be simulated through a slightly lighter rifle. The difference between the two averages remains just about constant as the rounds move downrange to the 500-yard mark where the averages for the WM and WSM are 58.2lb/f.s and 22.3lb/f.s respectively. From this data set, the .300 Win Mag still has a slightly higher sectional density than the .300 WSM rounds. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. Below we have listed the average recoil energy from all forty rounds we have compiled. Outside of the bullet design, which is going to provide controlled expansion to deliver penetration as well as deliver the huge amount of kinetic energy this bullet carries, it also carries a ton of momentum. The .300 Win Mag has also been used by snipers in special forces and military circles, but the majority of its use is in the hunting world. The difference in how low the bullet sits in the casing is negligible and results in the .300 Win Mag being able to hold a greater amount of powder though the case capacity does not represent how much powder is loaded into each cartridge. We are not stating here that penetration depends solely on the sectional density of the bullet. A bullet’s flight path has a characteristic arc with the bullet dropping in elevation over time. I currently have both a 700 Remington and a M77 Ruger type rifles. And you can never minimize the impact the person holding the rifle has on accuracy. Just looking at the muzzle velocities, we see three rounds that outperform the others with two of them being .300 WSM rounds and one .300 Win Mag round. The .300 Ultra Mag can fire the same weight bullet approximately 200-300fps faster than the .300 Win Mag. We didn’t see any huge difference in velocity from the averages of the cartridges out of the muzzle. Most weights are within the 150-200 grain range, but there are several lighter and heavier rounds available. Some people like a little extra velocity out of the muzzle, especially long-range shooters, and there are .300 WM and .300 WSM rounds that give you that. One way to think about this is as such: a foot-pound is a unit of energy equal to the amount of energy required to raise a weight of one pound a distance of one foot. We also tried our best in selecting a sample that contained some different styles of bullet and bullet weights. Understanding this information is crucial because when bullets fall below supersonic speeds, the flight becomes less stable and the bullets become more susceptible to environmental factors. Both of these cartridges can be hand loaded to give better performance specs. Those heavy rounds at 1,000+ yards appear to bring the average down a good bit at this range. The 300 WSM is a rebated rim, short-action round that fits 308-length rifle actions. Is this difference significant in the relation of cartridge to cartridge comparison? It has slightly less powder capacity than the standard length .300 Winchester Magnum. Trajectory is one of the most discussed ballistic properties when it comes to discussing the performance between different rounds as well as between two different cartridges. An examination of the long flight path of both cartridges over a 500-yard range shows a notable difference as the 300 Win Mag would be significantly flatter than the 308 . Again, there is not really a significant difference and the rounds from each cartridge are interspersed pretty evenly if we were to graph them. Below are the averages for all forty rounds that we compiled for this article. Some of this reduced weight often comes from using a shorter barrel, and there are a lot of arguments out there for longer barrels increasing the accuracy of the round. The .300 WSM achieves what its designers intended, duplicating the velocities of the .300 Win Mag from a short, lightweight rifle platform. Again, like most of the other categories, there is a lot of overlap between the two cartridge types, at least with the rounds we have selected. It is used for both big game hunting as well as benchrest target shooting. And given that we are dealing with two cartridges that are known for their incredible knockdown power, this is an important section if your choice is coming down to these two cartridges. The .300 Win Mag rounds have an average of 80.0lb/f.s while the .300 Win Mag has an average of 77.12lb/f.s. So your rifle is going to be a major factor in the velocity of these rounds being a pro or con. While we will look at each separate from the others, they should all be taken into account when determining which cartridge would be more advantageous in a certain situation. When it comes to hunting big game, there is one advantage for the .300 Win Mag, and that is the bullet size. And as we mentioned before, there are .300 WSM rounds that use the 200-grain bullets, but we have come across a lot of problems that people have when feeding these large bullets through short action rifles. The short magnums, such as the .300 Winchester Short Magnum, were excluded from this test since they just duplicate their larger cased cousins’ performance but in short-action rifles. The .300 Win Mag burns 20% to 25% more powder than the .30-06 Springfield, which gives it a 10% increase in velocity, as long as it is firing bullets of the same weight. Velocity is also important when it comes to stopping power. If we look at the averages, the .300 Win Mag rounds have a slightly higher BC at .553 while the .300 WSM has an average of .520. From the muzzle, all of these rounds show bullet energy levels greater than 3,400ft.lb with two of the Win Mag rounds showing greater than 3,700ft.lb of energy. Felt recoil takes a lot of other factors into account that is difficult to put numbers with. It can skew the data a bit but don’t make the mistake of thinking that there are not .300 WSM rounds out there that can give you the same performance. These characteristics are also advantageous to hunting large game where shots greater than 300 yards are common. The flattest .300 WM mag round has a bullet drop of 2.2″ while the flattest .300 WSM round has a bullet drop of 2.6”. So a .300 Weatherby Magnum round exits the barrel with kinetic energy equal to the energy required for linear vertical displacement of 4070 pounds through a one foot distance, while a .300 WSM Winchester Short Magnum round exiting the barrel has energy equal to the amount required to displace 3580 pounds over the same one foot distance. And that is usually a tradeoff you get with heavier rounds. In the table below, we have listed the averages of the forty rounds we compiled and their short range trajectory numbers. Which is several inches better than any of the other Win Mag and WSM rounds. Besides trajectory, the bullets ability to resist drag and wind resistance is also a factor in helping accuracy. We have also a 1,000 yard mark for further comparison. For long range shooting or chasing a bull moose, both of these cartridges, when shot with confidence and skill, are going to put meat in the freezer. There are flatter and steeper rounds for each and the steepest is only a little over 12″ at 300 yards, which is more than manageable with today’s rifle optics and a little hard-earned experience. Both have rounds with very high BCs and both have rounds on the lower end of the scale.

The concept of short magnum rounds was to provide the power and speed of magnums but allow the cartridges to be used in lighter rifles. We also think that it is important to note that though we are looking at all of these categories individually and that is only giving you part of the picture. It has a range of bullet weights from 125 to 200 grains though most would agree that the 150-180 gr bullets often work the best with the cartridge. We also do not see the rounds for each cartridge grouping together. The .300 WSM (Winchester Short Magnum) is the most popular and widely distributed of the modern crop of short magnum cartridges in terms of both factory loaded ammunition and rifles available. Find Bulk 300 win magnum ammunition fast and cheap with Americas best ammunition search engine. Both of these cartridges are a bit more expensive than other centerfire cartridges, but they also bring a lot more to the table regarding stopping power and ballistics. We also want to note that all of the data here is computer generated. The .300 Win Mag can be packed with large amounts of powder giving it a huge advantage in velocity. So, with all of that out of the way, let’s jump into our comparisons. The decision for which round is better for a given application should be made with complete information, and this article simply serves as a comparative guide, not the final say. Even at a distance of 500 yards, all rounds are supersonic with velocities well above 2,000ft.s. Keep this information in mind as we start to look at the actual data comparing these two rounds. They are the same manufacturer, the same bullet design, the same bullet weight, and very similar BCs. In American Whitetail, 6.5 Creedmoor costs $0.90/round, and.300 Win Mag costs $1.20/round. With that, in this set of ten rounds, the flattest round was a .300 Win Mag round, but we also saw a .300 Win Mag round that was the steepest in bullet drop. Furthermore, the muzzle energy of a .300 Weatherby Magnum round averages out to 4070 ft-lb, while a .300 Winchester Magnum round averages out to about 3520 ft-lb. And that change in the difference is mostly due to the.300 WM Trophy bonded ammo from Federal which only has a bullet drop of 6.6”. It’s nothing we can look at with these ten rounds under our criteria, but it’s something we thought you would like to take into consideration and research a little more on your own. Velocity is an important property of bullets for several reasons. Still, a lot of people like high velocity and feel that their rounds perform better with a little extra speed. 300 short Mag and im buying a 300. WSM for larger game, you will see that the begin!
