The PPU .300 AAC Blackout 125gr HPBT (brand part no. PP300BH) is a supersonic Blackout load built around a 125-grain hollow point boat tail bullet, a proven weight for wringing full-velocity performance out of short-barreled ARs. PPU — Prvi Partizan, producing ammunition in Serbia since 1928 — loads the round in non-corrosive, boxer-primed brass cases from its Standard rifle line, built on quality components for accuracy and dependable cycling. The boat tail profile helps the bullet hold velocity downrange, making this a solid choice for range work, training, and hunting-weight practice in any .300 Blackout platform. Among rifle ammunition, this PPU load favors Blackout shooters who want affordable brass-cased supersonic ammo by the box.

Frequently Asked Questions

Is this load subsonic or supersonic? Supersonic — the 125-grain bullet runs at full .300 Blackout velocity. For hearing-safe suppressed shooting, choose a dedicated 190-220 grain subsonic load instead.

Will it cycle a short-barreled AR pistol? The .300 Blackout cartridge was designed to burn its powder efficiently in short barrels, and this supersonic load is built for reliable cycling in AR-pattern rifles and pistols.
