“9 mm”

As a hunting cartridge, the 6.5-284 Norma has been touted as one of the best for game animals up to the size of elk.

What Winchester sought to do in 1958 was to provide those hunters who pursued the great bears and larger cervids of North America with a perfect choice for their endeavors, as well as developing one the most logical choices for an African light rifle. The result? The .338 Win. Mag.

While there are many cartridges that can handle medium-sized game, the .243 Winchester sits at the top of the heap for good reasons: it’s accurate, easy on the shoulder and delivers enough energy for the task at hand.

In spite of the numerous developments in handgun cartridge technology over the last century, it seems that the John Browning designed .45 ACP is as valid and as ever, and we'd bet that assessment will be valid in another 100 years.

Though the .223 Remington has stolen the limelight—military adopted cartridges tend to do that after all—we owe a debt of gratitude to Mike Walker and his development. Without the .222, there would be no .223.

What is it about the veteran cartridge that still appeals to shooters to this day, when there are so many more powerful cartridges available, including the Elmer Keith-upgraded .357 Magnum? Philip Massaro has the answer.

There’s no denying that the .270 has been getting the job done for over 90 years, with very few complaints.

You’ll see the .300 Win. Mag. in the hands of military snipers and big game hunters alike, with good reason: It just plain works.

The .470 Nitro Express has proven itself as a perfect choice for truly large game for more than a century now, and it won't be going away anytime soon.
