This segment covers the good and bad of the popular short magnums. We take the extra step and put extra-high-velocity cartridges to the test! Listen in for Thomas Tabor’s final thoughts on short magnums. If you missed Part 1 or Part 2, be sure to check them out!
I wouldn’t want to discourage any shooter from taking full advantage of this new era of cartridges. I would only ask that you become knowledgeable about both the positive and the negative aspects of these cartridges. When a detailed comparison is made between the muzzle velocities produced by the .300 WSM and 7mm WSM cartridges with those of the .300 Win. Mag. and 7mm Rem. Mag., the differences on paper are essentially minor…particularly in the case of the two 30 calibers. The same applies to the Remington SAUMs.
But even as such, some shooters would argue that differences in rifle performance are never solely limited to the data found in trajectory and ballistic tables. I would have to agree. So on that basis, if you feel the performances of the short magnum cartridges are worthy of consideration, by all means jump at the chance to try them. Part of the fun in shooting is trying new things and evaluating how they perform. Even though I experienced a significant amount of what I would call minor irritations making the transition into the world of short magnums, those have now been ironed out.
Overall, I was quite pleased with the performance of the 7mm WSM. As far as whether the WSM performed any better than a rifle chambered in 7mm Rem. Mag. is simply a question that will have to remain unanswered. I only know that a huge amount of game was taken with my 7mm WSM, and I would have to say that there wasn’t a single time that I regretted picking it as my hunting partner.
SHOULD YOU STOCK UP NOW?
Whether by simple scarcity, or a cartridge being discontinued, the odds that a specialty cartridge will be hard to come by when you need one are pretty high…so you should definitely plan to reload. These cartridges take common primers, common powder, and common enough projectiles…but their big limiting factor is brass.
With a case trimmer and reasonable charges, you should be able to get three reloads from each piece of once-fired brass (though not too many more). Acquire as much brass as you can, all at once…and never pass an opportunity to acquire an emergency reserve. Shoot through it all before reloading any piece a subsequent time, and it should all wear the same…giving consistent performance from rounds in a given batch.
