Ran some pellets across chrono. AA 7.33 about 620 FPS. AA 7.87 around 600. AA 8.4 around 570. Good accuracy with all, all a little north of 6 FPE. Wanted to test some wadcutters. Grabbed some 8.2 Meisters. 450 FPS. 460 FPS. Thought the spring had broken. Nope. Put AA domes back in and it does its thing. Anyone else ever seen this? Or have another wadcutter that works well in the 300S?
