Just bought a Tikka T3x TAC A1 went to install my Thunderbeast CB mount, but I ran into a problem, and I know I can't be the first. For whatever reason, Tikka did not put an undercut or relief cut between the end of the threads and the square face of the barrel shoulder. Not only is there no relief cut, it appears that the stub that is left between the threads and the shoulder are just a tiny bit larger in diameter than the threads. If I am measuring correctly, the major diameter of the threads is 0.623", which matches what Thunderbeast shows on their thread specs. But that remaining unthreaded portion measures 0.625". I'm trying to attach a picture of the muzzle, but this is a first for me on this board, so ....
The problem I'm having is that the peel washer included with the CB brake just won't go over that part. Yep, that 0.002" is giving me fits. It's a close fit over the threads, and it just won't go over that little stub.
So, how did you guys get past this?
Obviously, I could box it up and send the barreled action to Thunderbeast or Adco, but that's really annoying to have to go through that hassle and lose that time that I could be spending working with the rifle.
I thought about trying to open up the peel washer by just a couple of thousandths, but I don't have access to anything other than typical home power tools and hand tools. Also, not sure whether a peel washer would de-laminate during that process. I could buy a set of these from Brownells, and maybe they're just that tiny bit larger that they'll work as-is, or I could probably find a machinist to ream them out just enough to slide over that stub.
Any other suggestions? Like I said, someone else has to have dealt with this.
