I've tried every powder mentioned and more but I still come back to AA-2460.Can't seem to find a bullet that doesn't like it. H-335, AA-2230, and TAC are very close. IMR-4320 and 60gr Hornady S.P. bullets shoot bug holes in my old Ruger 77V 2 tone. Get busy reloading and try some different powders. Keep us posted.
