supersonic vs subsonic from a supressed rifle

PEW Science Research Note 2: The Rugged Razor762 exhibits a PEW Science Suppression Rating on the subsonic 300 BLK mini Fix bolt action test platform that is on par with other silencers of its size tested by PEW Science, to date, other than outliers such as the CGS Hyperion K (Review 6.50).

The relatively severe early time jetting is one commonality observed in the signatures the duration of amplitude, along with duration of decay, differs across the designs. All three silencers are compact all use a different type of baffle implementation, expressed in their external early-time signature histories (ref. PEW Science Research Note 1: The Rugged Razor762, when used with subsonic 300 BLK on the tested platform, shares some signature similarities with that of the YHM Resonator K (Review 6.30), and the SilencerCo Omega 9K (Review 6.62). The Rugged Razor762 represents one of the lowest baffle count Rugged rifle silencers in the lineup the short configuration of the Rugged Radiant notwithstanding. The Rugged rifle silencer designs, while not as highly advanced as some newer technology, or purpose-built for 300 BLK suppression like some other technology, are still able to significantly suppress subsonic 300 BLK signatures when scaled to a higher baffle count. The Rugged rifle silencer designs were one of the first case studies used by PEW Science for Omega Metric flow rate validation due to their early-time shock wave reflection and flow characteristics (the so-called PEW Science Alpha parameter) being effectively constant across models.

Because all of these silencers have similar geometry in their first wave expansion regions (blast chambers), the scaling of their designs results in holistic weapon functional influence that strongly correlates with the PEW Science Omega Metric research parameter referenced above (ref. Its baffle count is 2 fewer than the short configuration of the Rugged Surge, and one more than the Rugged Razor556 (and the modular Micro30). The Razor762 contains 4 baffles, which are of curved-cone geometry. The Rugged Razor762 is relatively compact for a 30 caliber rifle silencer and shares extremely similar internal geometric features with other Rugged rifle silencers such as the Rugged Surge (Review 6.22 7.62x51mm bolt action), Rugged Radiant (Review 6.12 7.62x51mm bolt action), and also its sister silencer, the Rugged Razor556 (Review 6.76 5.56x45mm semiautomatic).
