The SS109 is the US Military’s terminology for the 62-grain steel-core penetrator round, designed to provide enhanced barrier penetration compared to common 55-grain projectiles.
NOTE: While the 5.56x45mm NATO round will fit in a .223 Remington chamber, 5.56 NATO is a military round that runs at higher pressures, and is not recommended for use in .223 Remington chambers.
