Frequently Asked Questions

What Is the Most Common Rifle Ammo?

The 22 Long Rifle is arguably the most popular rifle cartridge today, partly because it’s not exclusive to rifles, despite its name. Many handguns also fire 22 LR, and this versatility, plus the caliber’s long history, make it one of the most widespread ammo types today.

Other common rifle ammo includes the .223 Remington and 5.56 NATO, thanks to the enduring popularity of the AR-15 platform. The U.S. alone is home to over 20 million AR-15-style rifles, so ammo manufacturers produce a lot of ammo to meet this demand.

The 6.5 Creedmoor and .308 Winchester round out the rest of the five most common rifle ammo types today. GunMag Warehouse proudly stocks all of these popular calibers in multiple brands, applications, and round counts to help you get the best ammo for your needs.

Can You Use .223 Ammo in a 5.56 Rifle?

While the .223 Remington and 5.56 NATO appear almost identical to the naked eye, you shouldn’t fire one in a rifle chambered for the other. Despite their many similarities, there are slight differences that can pose safety issues to you and your firearm.

You can shoot .223 ammo out of a 5.56 safely, however, the 5.56 is designed to withstand higher pressures, and a 5.56 round’s slight size and shape discrepancies can create excess pressure in the chamber of a .223 rifle. While some shooters debate how much of a real-world difference this makes, it’s best to play it safe and stick to the ammo your firearm is designed for. 

What Ammo Does a Bolt-Action Rifle Use?

There is no specific type of ammo exclusive to bolt-action rifles, and ultimately, you should use whatever caliber your firearm is chambered for. However, there are some ammo types that are more common in bolt-actions.

Bolt-action rifles are popular among hunters, especially in states with tighter restrictions on magazine capacity and “assault”-style weapons. Consequently, hunting ammo, which emphasizes reliability and precision, is a popular choice for bolt-action owners.

Similarly, some shooters prefer straight-walled cartridges in their bolt-actions because of local restrictions. While straight-walled cartridges are most common among lever-actions, some bolt-action rifles can use these, too.
