Maxim Defense MXM-49005 .300 AAC Blackout 190gr Solid Copper SBA 20-Rd - Box or Case

The Maxim Defense MXM-49005 is a heavy, subsonic .300 AAC Blackout load purpose-built for short-barrel platforms, featuring a 190-grain Solid Copper Spun (TUI) projectile seated in a brass case. Part of Maxim's SBA (Short Barrel Ammunition) line, this round is engineered to deliver reliable cycling and consistent performance from compact rifles, AR pistols, and suppressed SBRs chambered in .300 BLK.

The all-copper, lead-free bullet promotes consistent expansion and high weight retention, making this load well-suited for hunting, training, home defense, or general range use from short-barrel and suppressed .300 AAC Blackout firearms. Loaded to 20 rounds per box with 25 boxes per case (500 rounds total), this ammunition is ideal for stocking up on quality .300 BLK for the range or the field.
