    I shimmed the scope base and now putting together some rounds. Just for the heck of it I loaded a dummy round to the sierra spec for the 165 gr HPBT game king 2.800 smoked the bullet and run it thru the chamber with the bolt. WOW..Got marks where it was hitting the rifling. All around too. I thought the book recomendation was on the short side..

    Anyway..Kept sitting the bullet deeper until I saw no more marks from the rifling. Ended up with 2.765. Should I trust this? I figured it would of been longer??

    Maybe time for a stoney point [​IMG] Could this be a reason my groups were for poop yesterday. C.O.A.L too long??
