I use IMR 7828 SSC . I use 61.0 grains of 7828 ssc with a 160 grain Barnes x flat base bullet . I shoot key hole groups every time . I bump up the grains to 65.0 for elk or moose . I hope this helps Joe Lafortune CD
H4831sc has worked very well in the limited work I've done with 7mm RM.
This post never answered the question iceman asked
bigbullCode:What caliber 7mm.........
