Bulk Ammo for Every Caliber
BulkMunitions stocks more than 60 calibers of rifle, handgun, rimfire, and shotgun ammunition, from high-volume range staples like 9mm, 5.56 NATO, and .45 ACP to newer cartridges like 6mm ARC, 7mm PRC, and 30 Super Carry. Every caliber page lists only ammunition that is physically in our Knoxville, TN warehouse, and orders placed before our daily cutoff ship the next business day.
Most loads are sold in full factory cases of 200 to 1,000 rounds, which deliver the lowest cost per round. Each caliber page includes brand filters, recommended loads for range training, self-defense, and hunting, and answers to the most common compatibility questions for that cartridge.
How to Find the Right Caliber
The correct caliber is stamped on your firearm’s barrel or slide. Always match that marking exactly. Some cartridges look similar but are not interchangeable, such as .223 Remington and 5.56 NATO, .308 Winchester and 7.62x51mm NATO, or 300 Blackout and 5.56. Others work in one direction only. A .357 Magnum revolver safely fires .38 Special, and a .44 Magnum revolver fires .44 Special, but not the reverse.
If you are unsure which ammunition your firearm takes, check the barrel marking or your owner’s manual before ordering, or email us at sales@bulkmunitions.com.
