Another 100 rounds of Norma Tac22 at 25 yards, then Match at 50. New barrel is coming around. I was able to shoot 95-96 timed fire targets and 11 of 18 rounds in the 10 ring at 50 yards from a wrist rest, in a medium cross wind. No failure to fee but not cold today, just low 50F temp. I cleaned the barrel with Kroil and some tight patches and then ran a pellet with some JB bore paste up and down the bore, cleaned all of that out, and then 'scoped it. The tooling marks from the reamer have smoothed out, the lands look perfect, no rough spots, bore looks excellent, at least to me. A little carbon in the throat area but no build-up. That is what I have to watch for, I think, and keep down, now matter what. I am going to 'scope and clean this barrel after every range trip and see if I can keep the chamber area clean and smooth for a change.
My opinion is that this barrel smoothed out and is stable after about 200 rounds, perhaps much less, like close to 100, based on the observation that I didn't have any bad results today at all. I was not steady myself but I was able to call all the bad shots during timed fire practice, and that means the bullets are hitting where the dot was pointed when the gun went off.
No more testing. I am going to just go back to my regularly scheduled bullseye practice sessions, now that I know the gun is back to 100%. Time to get the shooter back to 100%. May take a few weeks, LOL.
I may try to do a borescope video comparing the old and new barrels on Saturday. Maybe.
