HPR (High Precision Range) Ammunition is blacking out, with a bit of help from Barnes. The Arizona ammunition maker is adding a .300 Blackout offering to its catalog and is topping off the cartridge with a 110-grain Barnes' TTSX bullet.
The TTSX, released in 2003, was designed as a hunting bullet. The streamlined projectile has a polymer tip that helps reduce drag and increase the ballistic coefficient. It also aids in the solid-copper bullet's expansion.
The TTSX has won praises for its terminal ballistic performance. The bullet retain nearly 100-percent of its weight and it double in diameter, both leading to wound channels.
HPR puts the muzzle velocity of its new 300 Blackout ammunition at 2,311 fps and its muzzle energy at 1,304 ft./lbs. The ammunition is presently available in boxes of 20, which have an MSRP of $33.99.
