Up first were the subsonic loads.Īll shots were fired from my Savage Mark II (16-inch barrel, 1:16 twist rate) into blocks of ten percent gelatin from a distance of ten feet. 22 LR ammunition currently in production, I decided to tackle the project by testing a selection of ammo from three different categories: subsonic (under 1,126 f/s MV), standard velocity (1,126 to 1,300 f/s MV), and high velocity (over 1,300 f/s MV). 22 LR rounds into gel blocks and compare the results.
