The Sig Sauer Elite .300 AAC Blackout 120gr Copper (Sig Sauer part no. E300H1-SBR-20) is a .300 AAC Blackout load built around a 120-grain Copper for personal defense and everyday carry. Sig Sauer builds this load for shooters who carry every day and need a bullet that performs on the first shot. This load uses an all-copper, lead-free projectile and a propellant tuned to perform consistently out of the shorter barrels common on SBR-length AR platforms, where standard loads can lose meaningful velocity. For rifle ammunition, this is a load built to feed and perform reliably out of a home-defense or duty-grade rifle.
