It's a semi custom Rem 700 action bartlein barrel. After shooting that particular bull I switched to berger 215 hybrids. Hybrids grouped better, only reason I switched. I've shot several whitetails with that gun since. Ranges from 10-300 yards. No issues all drt.
I have a Athlon ares ETR 3-18 coming soon which is right at $999. I can compare it to a PST gen 2 once I get it, if that's something your interested in.
I love my 7 saum. I'm shooting 180 berger hybrids at 2930fps. 3.070 coal. Adg brass 60.7 grains of H4831sc, fed 210m's. It shoots .3 moa at 600 yards. Action is a medium lone peak fuzion ti. 26" proof sendaro lite. TS customs put it all together, to bad its my wife's gun!!
