This video features a comprehensive test of three different types of 300 Blackout subsonic ammunition, including Federal 220 grain OTM, Hornady 190 grain Sub-X, and Hornady Black 208 grain AMAX. The testing is conducted using a Sig Sauer Rattler LT pistol and a Surefire 300 SPS suppressor. Key performance metrics evaluated include flash suppression, noise suppression, gas operation, fouling, and shot group size. The presenter also discusses factors relevant to the Sig Sauer Rattler LT, such as barrel twist rate, and uses a Lancer 20-round magazine for reliability assessment.
