I have tried many bullets from 240-250 cast Keith style, jacketed, etc., and the most accurate load for me from my 7.5 inch SBH is the Cast Performance LBT 320 grain LWNGC over 21 grains of WW296. Clocks close to 1300 fps with no pressure signs and shoots an inch or less from 50 yards.....this year, one shot, one kill, at 97 lazered yards.....works for me.
