The 6 Best Rifle Calibers: Popular Centerfire Chamberings

By Chris Eger

While it may be difficult to discern just what makes the best rifle calibers these days, one easy bar with which to gauge popularity is sales numbers.
For this, Guns.com consulted the experts at Ammunition To Go who came back with a rundown of the six most popular cartridge sizes when it came to centerfire rifle ammunition over the past three years. The list may just surprise you.

The good old rimmed military cartridge invented by Russian Col. Sergei Mosin back in 1891 is still kicking today. Used in Mosin’s long-running series of bolt-action rifles, which are arguably the most prolific infantry weapon of the 20th Century, the 7.62x54R is still in active use in various machine gun and designated marksman rifle designs today while some new-made Vepr models continue to utilize the round. It is no wonder that the cartridge, with similar ballistics to .30-06, has proven a best seller on this side of the pond in recent years.
