This barrel didn’t shoot very good for a while. Figured out After about 150 rounds that it hated when the bipod was loaded... it’s sittin in a XLR chassis but it just doesn’t like that. Started shooting free recoil technique and groups shrunk a bunch. Found a load today with 75 Berger VLD and h4895 that shoots sub .4” pretty consistently .005 off the lands. Seems to be getting a little better the more I shoot it .
