I had GAP build off my M70 action. It's a 7WSM, 26" 5R Bartlein Barrel, and Manners T3 stock. It's nothing fancy but shoots outstanding. My first try at 917yds didn't do too bad on this 10" plate. I'm sure a better shooter could really tighten the group up a lot. This was my first attempt at this range. I had it built mainly for antelope hunting in S.E. Colorado. We hunt a private ranch S.W. of Lamar and you can see to the horizon in every direction.
My load is:
65.80gr H1000
CCI BR2 Primers
Winchester brass
180gr Berger hunting VLD
2.2475" Base to ogive
2,880fps @ 57 deg, alt. 1,374ft
100yd C/C 5 round group 0.116"
