Rotating the gas-port valve so that the “H” for high velocity ammunition was facing the shooter helped the gas impingement system deal with higher pressures. Adjusting for lower-velocity rounds that produced less pressure assured that the bolt would cycle reliably. High-velocity rounds produced recoil on about the same level as a 5.56mm/223 Rem AR-15. Even without a compensator, recoil from low-velocity rounds made our SSK carbine feel like an air rifle.
For comparison we bracketed five of our 300 Whisper test rounds between a 223 Remington (left) and a round of 308 Winchester. Our test rounds included a Cor-Bon 150-grain JSP, a handload topped with a 169-grain Hornady HPBT bullet, Cor-Bon’s 220 grain, Cor- Bon 125-grain, and Hornady’s 208-grain A-Max.
Our test gun was the basic model. SSK Industries is owned by J.D. Jones, inventor of the 300 Whisper cartridge. Note the unusual barrel twist, 1:7.5.
