I bought a box of 140 SGK 140gr and with 43.9 gr (worked up to carefuley) and with no real pressure signs this rifle willl shoot .450 very comfortably in 92 degree weathwer. I can't ask for much more than that!! I carefully lapped the bore before it was shot the first time and went through a normal breakin procedure (shoot 1 and clean) through 5 shots and shoot 2 and clean through 10 and now it collects little if any copper and shoots lights out...for a factory bbl and nothing else!
Thanks for the replys and keep them comming!!!
