The gunsmith for this build was Terry Cross from KMW Longrange so I have faith in the work. I actually measured my barrel Saturday and although I was told it was 24" it actually measures 25.25" from crown to bolt face so that explains some of it.

I'm playing with seating depths now and groups are still good, speed is still averaging 3025fps but SD is down to 4.4 for the last 20 rounds.

I've read couple articles about your gunsmith and one being on 6BR site about rifle he build. I don't know how many but Brux,Kreiger,Chanlynn,Rock Creek all got their start working for Obermeyer so you have good barrel.

Well good luck
