Always consult current published reloading data from a reliable source when selecting components and developing a load. Verify that the data being used is appropriate for the cartridge, bullet, and other components being used.

Frequently Asked Questions (Click to expand)

Q: Are these bullets .223" or .224" in diameter?
A: These bullets have an actual diameter of .224". The .223 designation refers to the .223 Remington cartridge/caliber, while .224" is the specified diameter of the bullet itself. Cartridge names do not always correspond exactly to the measured diameter of the projectile, which is why a bullet intended for .223 Remington reloading may be identified as a .224"-diameter bullet.

Q: Are these Full Metal Jacket bullets?
A: Yes. These are Full Metal Jacket (FMJ) bullets with a copper-jacketed construction.

Q: Do these bullets have a boat-tail base?
A: Yes.

Q: Do these bullets have a cannelure?
A: Yes.

Q: Does the cannelure determine where the bullet must be seated?
A: Not necessarily. The cannelure provides a defined location where a case mouth may be crimped, but its position alone does not determine the correct seating depth or cartridge overall length for every load. Reloaders should reference published load data appropriate to the cartridge and components being used.

Q: Do I have to crimp these bullets at the cannelure?
A: Not necessarily. Whether a crimp is appropriate can depend on the cartridge, firearm, loading application, and other factors. Reloaders should follow applicable published reloading data and the instructions for the dies and components being used.

Q: Are these bullets intended for .223 Remington reloading?
A: Yes. The manufacturer includes its 55 grain FMJ projectile in published .223 Remington reloading data.

Q: Can these bullets be used when loading 5.56 NATO?
A: These .224"-diameter bullets may be used with cartridges for which appropriate published reloading data supports their use. Reloaders working with 5.56 NATO should reference current published data specifically appropriate to the cartridge and components being loaded rather than treating .223 Remington and 5.56 NATO load data as interchangeable.

Q: Can I use load data for another 55 grain .224" bullet?
A: Not all 55 grain .224" bullets are identical. Bullets from different manufacturers can vary in construction, profile, bearing surface, and other design characteristics, even when their diameter and weight are the same. Reloaders should reference current published data appropriate to the specific bullet and components being used whenever possible.

Q: Are these loaded .223 cartridges?
A: No. These are component bullets/projectiles for reloading, not loaded ammunition.

Q: Where are these bullets made?
A: These bullets are made in the USA.

Loaded and shot 200 of these and was impressed with the results. Accurate at 1 MOA and easy to load. All that I weighed were consistant as Hornady. Loaded a few to 3,000 FPS and was impressed by how flat they shot. Will be ordering more, about the most inexpensive bullet to shoot.
