Got back from the range last Sat. The 15 MOA scope base did the trick. But with the stock trigger and bolt my buddy won't get any better than a 2 1/2" group at 50 yds. If he opts for the trigger kit, CNC machined bolt and a MADDMACS comp, he'll cut that in half because that's what I'm getting @ 50 yds. Shot Winchester wildcats, Federals BYOB plated. Wildcats were ok but the federals grouped better. Tried some CCI mini mags but wasn't spectacular. He wants something to keep the wild doggies away.
