Pitted Carcano Barrel

Thanks, I would be very happy with that group! I’m changing out the front sight so it doesn’t shoot two feet high. I may try some more fire lapping if the FMJ doesn’t group better. If the bore opens up I will just use cast in it.

Just for your interest.
I had a 22lr once.
It would only shoot after I slurped some lube down the barrel after cleaning.
It had a few bulges and things.
It shot good till you cleaned it again.

Fire lapping is very much one of those "Don't over do it" propositions. A little is great, lots wreck things.

The thing is, it doesn't uniformly lap. The action is MUCH more aggressive in the throat. You'll extend and wash out your throat in a hurry, but not do much else to the rest of the barrel.

If the barrel is too messed up to be a good shooter - sell it and buy one with a better barrel.

I’m not going to waste anymore time conditioning the bore. I will try to shoot it one more time with different loads and see what I get. I would rather trade it and pay more to get something better. It’s hard to give up on a milsurp!
