Going to shoot my FWB 124D with 12x scope (front objective adjustment) at a FT competition next year. May even shoot Gunslynger at the Pyramid cup. I know my setup puts me at a disadvantage but want to try it before spending more money for a more competitive setup. Just doing for fun so may not upgrade anyway. I think the distances are from 8 yards to 55 yards. My gun is shooting close to 800 fps with JSB 10.3 grain. What distance would you zero at?????
