Hi folks it's been a while since I last posted on here and I always seem to be begging for knowledge! I have in my workshop a BSA Superten ( a heavy beast) in .22. The sad little thing is only making 8.5 ft lbs average over a string of 5 shots. I know better than anyone not to ask for a secret formula to take it above legal but somewhere in the 11 ft lb region would be nice. Many thanks in advance.
