Thanks Dan, already tried that. After glassing, barreled
action is rock steady. I shoot only handloads: W748, N133,
Benchmark, Norma 200, IMR4198...same result.
Sent it back to my gunsmith buddy for another recrown job.
He says previously the cutter pilot was wobbling in the bore. After whacking another 1/2inch off, the pilot is now
a snug fit. Possibly a bad barrel that was over-sized at
the muzzle. I'll shoot it again Tuesday.
Thanks for the input gents.
