.300 Winchester Magnum - BallisticStudies.com
There are still many manufacturers chambering the .300 Win Mag in rifles that feature short magazines, potentially (but not always), producing less than desirable and sometimes frustrating performance with hand loaded long for caliber projectiles. A minimum internal magazine length of 90mm (3.543”) should be sought for best results.

The .300 WSM achieves what its designers intended, duplicating the velocities of the .300 Win Mag from a short, lightweight rifle platform. Generally, the savings in length are approximately 2.5” when using a 24” barrel as opposed to the optimal 26” barrel length for the .300 Win Mag. Nevertheless, there is no free lunch.
.300 Weatherby Magnum - BallisticStudies.com
Based on the .300 H&H case blown out to maximum capacity, the .300 Weatherby Magnum was introduced by Roy Weatherby in 1944. Although the case design of the Weatherby was entirely different from the .300 H&H, enabling head spacing at the shoulder, Weatherby retained the belt at the case head, resulting in a very successful marketing ploy.
.300 Remington Ultra Magnum - BallisticStudies.com
The .300 RUM can be hand loaded to surpass factory velocities by a considerable margin. Also, unlike the 7mm RUM which struggles to better the velocities of the 7mm STW, 7mm Weatherby and 7mm-.300 Win Mag, the case to bore ratio of the .300 RUM achieves significant increases in velocity over other .300 magnum cartridges.
.264 Winchester Magnum - BallisticStudies.com
Inside 300 yards, wounding is very similar to the .300 Win Mag loaded with conventional 180 grain bullets. The performance of this particular bullet is unique and cannot be generalized. The 130 grain Barnes is better suited to game weighing between 90 and 320kg (200-700lb) while the 140 grain bullet, as can be expected, is better suited to game ...
7mm Practical - BallisticStudies.com
Some claim that the 7mm-300 Win Mag is nothing more than the 7mm Mashburn however this is not quite true. The 7mm Mashburn Super Magnum wildcat was based on the .300 H&H case shortened, blown out and necked down - not the .300 Winchester Magnum. The Mashburn was designed by Art Mashburn during the mid to late 1950’s.
.30-378 Weatherby Magnum - BallisticStudies.com
With careful load development the .30-378 can surpass the .300 RUM but once the factors of free bore, over bore (big charge / little bore), and cartridge case pressure ratings are understood, the shooter can set realistic expectations as to just how far the .30-378 cartridge can be pushed. .
.325 Winchester Short Magnum - BallisticStudies.com
The .325 WSM is the smallest of the WSM family. While the case length remains the same as its kin, the shoulder is set back 1.8mm or .074". It is possible to utilize .300 WSM cases as the basis for forming .325 brass, however the process requires a degree of hefty forming to obtain the desirable shoulder length reduction.
.338 Winchester Magnum - BallisticStudies.com
The 275 and 300 grain bullets can be used in the .338 Winchester Magnum for hunting large bodied non dangerous game at extended ranges, the reduced velocity aiding penetration of the fragmentary cluster. Berger produce a 250 grain Elite Hunter VLD bullet suitable for the .338 Winchester Magnum along with a 300 counterpart for the larger magnums.
.300 Remington Short Action Ultra Magnum - BallisticStudies.com
Major rifle and ammunition manufacturers have supported the .300 WSM and presently Remington have also adopted the .300 WSM in their M700 rifle line, the .300 SAUM barely surviving as a chambering for the model 7 rifle. Performance The .300 SAUM is a potent cartridge, whether chambered in the 22” barreled Model 7 or longer barreled rifles.
