The Rugged Razor762 30 caliber centerfire rifle silencer is evaluated with two types of subsonic 300 BLK ammunition in this members-only Research Supplement to examine its relative First Round Pop (FRP) and overall sound signature suppression performance characteristics. Performance of the Razor762 with Discreet Ballistics 300 BLK 190gr Target ammunition is compared to that with S&B 300 BLK 200gr ammunition. Impacts to the PEW Science Suppression Rating on the standard 8-inch barrel 300 BLK bolt action platform are investigated.

This research supplement is intended to provide more information to PEW Science members with regard to the specific sound signature characteristics of multiples types of subsonic 300 BLK ammunition. This supplement is part of ongoing PEW Science small arm weapon system sound signature research.
