odelkhunter....thanks for your reply. I' m using a stoney point oal gage and rcbs dies and reloading equipment. All my cases are trimmed to length and deburred including flashholes. I' ll take your advise and seat .020 and just keep going in and see what happens. I' ll start with what nosler recommends as being their most accurate powder imr4350 but i also have some 7828 and 4831 that i can try. Again thanks!
