I have a Savage 112 FVSS in a 300 win mag with a 26" varmint taper barrel, made in savage custom shop several years ago. I am using 190 grain berger hunting vlds and 210 vlds hunting. Having problems with points of impact changing and group sizes. Sorry, don't know all the terms, new to this forum. Trying to get gun to shoot under 3/4 moa at 100 yards. Does anyone else have this gun that is exceptionally accurate? What did you do to get it accurate? Any info or advice on this?
