Both of mine shot the rem 140 about 1" or less at 100 yards. Never tired and other ammo in them. My cousin uses 139 Honady sst in his and they shoot pretty good. My dad's friend use 139 bolsters in his sons model seven he seems to like them. A good friend loads 140 Barnes in his grandsons I like it is a cdl, he killed 5 or 6 Africa plains game with it last year.
