Oh, ans I fired 350 rounds before I realized I had a bad barrel. It was marginally bad.
350 rounds, 10 trips to the range, 350 primers, plus powder, plus lube, sizing, cleaning between experimental rounds, range fees, gas, sleepless nights, dejection, questioning my own skills (I now shoot 5 through the same hole at 200 yards....).
Dont let me leave out the HOURSS of solvent breathing joy of cleaning that MF all those times too (Full bottle of Sweets, shooter's choice, 1000 patches, 12 brushes...)
I would not wish that on my worst enemy.
Factory rifle???? Dont do that to yourself.
