“BenSeager”My 22 barrel was at 1048 before i bumped the reg tuning .30 barrel

 


That is waaaay too hot!
1. Soft lead pellets can lose their integrity at that speed.
2. You are risking damage to the shroud/end cap because of above. 
3. Unlike traditionally rifled barrels, SmoothTwist barrels operate best right around 900 fps or below. I believe Ted found the best accuracy with the JSB Heavies to be in the mid 800’s.
