My gun is done and he is doing a minor barrel break in. Gun comes in at 11.75 lbs with a 6.5-20x50 Leupold on it. He has 14 rounds down the barrel, two different groups shot. The first group shot measured in at .425 and the second measured .40. He used 49 gr. of H4350, behind a 140 gr. Berger Hybrid, with a speed of 2900 FPS. The speed should pick up a little with some more rounds. He hasn't played with the seating depth at this point. He said he is going to try some 4831 and see what he can get with that! He measured the barrel deflection before and after bedding. It went from 13 thousands to less than 1 thousands!
Finished test firing (30 Rounds). All groups averaged together was .370" with the smallest @ .176". Velocity is @ 2925 fps which will still increase as more rounds are put through it, it should end up at about 2975 fps when finished. Overall length of the rifle is 49 5/8".
Both loads, ES/20-30, SD/ low teens. Could be tighter but don't judge until break-in is complete. Sure can't argue with group size though. I shot only one 5 shot group @ 400 yds. with the IMR4831 load and it was just a bit over .5 moa. Wind and mirage didn't help much but still a respectable group from a brand new barrel.
