how fast you can push will depend on twist rate and alloy. For me in the 1:10 twist rifles for me really loosen up right around 2000fps.View attachment 483633
17.5 and the 19 grouped well. The two flyers in the 19 target were my fault. Some days you shoot good and others you don’t and today was not my best day. I still have to review the chrono but these were clocking below 1700 FPS. How much higher should I push these. Maybe ladder them up into the low 20’s with 2400? Oh and no leading and it did clean and check a couple of times at the range. That was from the 100 yard. And yes I spring for the fancy targets.
