You could do ALL, the work "necessary", ONE time, in about,.. an Hour and, a half !
NO need, to go back and forth to Range after, checking,. ONE,.. "item" !
I have only heard of, ONE Tikka that, was sent in, to the Tikka Factory for their, 1 MOA guarantee and,.. Failed !
I am, a retired Gun Smith, I read, a LOT of Posts on Here and on Accurate Shooter about Tikka's, ONE Rifle, actually, failed !
Heard it was missing a couple of inches of Rifling, near the muzzle and they apologized, profusely ( said that, they couldn't believe that, it had slipped thru, their, QC ! ) and sent him a New Rifle, I heard.
UNLESS you KNOW that, you have, either, a BAD Chamber or, a bad Barrel, I wouldn't waste, more,.. Time / Money !
Very, FEW, Tikka's,.. Fail !
