![]() In some cases, especially with the lightweight loads, the. However, this difference is really low and does not cross 100 fps, no matter which round you choose. At varying ranges, the velocity values for different rounds may differ. Here are the velocity and kinetic energy values of both these rounds for a quick overview.Īgain, the speed characteristics for both these rounds are almost the same. 300 Win Mag vs 300 WSM: Velocity & Kinetic Energy Both these rounds were designed for long range engagements, and they certainly do that with great accuracy. It will not be fair to give either of these an edge over the other, at least when the trajectory is concerned. The fact that there are many different rounds and each of them performs differently. 300 Win Mag but only by a few inches or so on long range. 300 WSM seems to have a little edge over the. It is true that different bullets will perform differently, and if you combine the average of the rounds available for these two cartridges. I used the same bullets to get an exact idea of how these rounds are going to perform. ![]() Except for the 165-grain variants, the other two bullet types show the same trajectory out to 1,000 yards. The comparison of trajectories for both these rounds is pretty much straight. Here’s a quick table defining how these rounds perform at short and long ranges.ģ00 Win Mag 24” barrel/BC 0.398/165 grains There are three major factors under ballistics, trajectory, velocity, and kinetic energy. This helps us understand if a bullet will be suitable for short, medium, or long range, or perhaps if the bullet is suitable for any specific application. The study of ballistics deals with understanding the behavior of a moving projectile at varying distances. Photo credit: 300 Win Mag vs 300 WSM: Ballistics However, this does not make these cartridges or rifle parts interchangeable by any means. 300 WSM has a larger base diameter, it uses a rebated rim to fit the bolt head. 300 WM has a higher ceiling for maximum weight and goes beyond 200 grains and up to 300 grains. Talking about the weight of the bullets, both these cartridges handle almost the same weight of bullets. 300 WSM has a 20% lesser case capacity, but it comes loaded at almost the same chamber pressure as the. 300 WM is already an innovatively designed round that fits standard actions and does not need a magnum length action. 300 WSM brings it down to a short action cartridge length. Indeed Winchester has fared very well on that promise. 300 WSM was to create a shorter version without compromising on performance. 300 WM, but in a slightly different manner. 300 WSM is just a shortened version of the. 300 WSM cartridges.Īs you can already see, the. Here’s a quick side-by-side comparison of the. 308 Winchester and fits a short action, making cycling quicker. 300 WSM uses a rebated rim design, using a rim diameter almost the same as the. Thus delivering uniform ignition of the propellant and slightly adding to the velocity. The purpose of developing a short magnum cartridge is to condense the gunpowder in a more compact space close to the primer’s flash hole. It eliminated the belted case and head-spaces off of the case shoulder 300 WSM is that it delivers almost the same performance as the longer. 300 Win Mag with lesser powder and a shorter overall length. It can be seen as a shortened version of the. 300 WSM is a rimless, bottlenecked, centerfire rifle cartridge introduced by Winchester on the market in 2001. 300 Winchester Short Magnum, also known as the. It is a very flat shooting cartridge and renowned for its power. 300 WM still survives and is extremely popular for big game hunting and long range competitions. 300 H&H Magnum which were similar in design, were introduced before the. It comes from a family of cartridges that can be fired from a standard/long action rifle and do not need a magnum chamber. ![]() This round was introduced by Winchester in 1963 after experimenting with a few other magnum cartridges before. It was slightly lengthened and the shoulder was moved a bit forward. 338 Winchester Magnum introduced in 1958. 375 H&H as the parent case, reducing its taper and shortening the neck to accept a smaller. 300 WM is a bottlenecked, belted, magnum rifle cartridge that fires a. 300 Win Mag that can do everything the same but in a smaller and lighter rifle 300 Win Mag Overview ![]()
