Fiocchi Hyperformance SBR Enhanced .300 AAC Blackout ammunition (brand part no. 300BKSBA) loads a 125-grain SST (Super Shock Tip) bullet, a powder charge specifically tuned to reach full velocity and expansion potential out of the short barrels common on .300 Blackout AR pistols and short-barreled rifles. Standard rifle loads can lose meaningful velocity in a barrel under 10 inches, robbing a hunting or defensive bullet of the energy it needs to expand reliably; Fiocchi’s SBR Enhanced burn rate is calibrated to avoid that penalty. The polymer-tipped SST bullet initiates rapid, controlled expansion on impact once it is running at the velocity this load is built to deliver. For .300 Blackout shooters running a short-barreled platform who want full performance, this rifle ammunition from Fiocchi is built for exactly that.

Frequently Asked Questions

What does SBR Enhanced mean? The powder charge is tuned to reach full velocity and expansion potential out of the short barrels common on .300 Blackout AR pistols and short-barreled rifles.

Does a standard .300 Blackout load lose performance in a short barrel? It can; barrels under 10 inches often cost a standard-burn-rate load enough velocity to compromise bullet expansion, which this loading is specifically tuned to avoid.

What is an SST bullet? Super Shock Tip, a polymer-tipped bullet that initiates rapid, controlled expansion on impact.
