223 Rem Ammo

Bulk 223 Ammo for Sale!

223 Remington is easily the most popular centerfire rifle ammunition in the United States. This is driven mostly by the fact that 223 Remington is the primary cartridge for the AR-15 platform, which happens to be the most popular centerfire rifle in the United States. The history of both the 223 Remington cartridge and AR-15 rifle are deeply intertwined with each other.

While overall a quite lengthy story, 223 Remington ammo was developed in concert with the AR-15 rifle as the military looked to move away from the larger, heavier 7.62x51 NATO round to something smaller and lighter, allowing troops to carry more ammo, and be more effective against armored targets. After much in-fighting between services and senior commanders, 223 Remington ammo and the AR-15 were designated 5.56x45NATO and the M16 respectively and adopted for service with the majority of US Armed Forces.

Initially, almost all 223 Remington and 5.56x45 ammo had 55 grain bullets, but modern 223 ammo has bullets available from 40 grains, up to 77 grains. Generally speaking, the lighter bullets are designed for varmint hunting with 223 Remington, while the heavier bullets are hollow-point boat tail bullets designed for competition or precision shooters choosing 223 Remington as their ammo of choice. It should also be noted that there are some differences between 223 Remington ammo and 5.56x45 ammo. 223 Remington ammo can be safely chambered and fired in a chamber cut for 5.56x45 (which is standard in most every AR-15 rifle today). However since 5.56x45 NATO chambers have a longer leade, it is not advisable to attempt to fire 5.56x45 NATO ammo in a chamber cut strictly for 223 Remington Ammo.
