GunGeek got it right. I you want minimum headspace, just don't resize the shoulder back. Anyone with a Bridgeport, or a good metal lathe can cut the boltface back to the bottom of the pockmark, and you are good to go. You prolly won't cut it far enough to need to move the barrel. Have fun, Gene

I like Sheister's answer. Straight-forward and won't change anything else if you like the way it shoots now. I think the trick is finding a gunsmith who really knows TIG welding and won't dump enough heat into the bolt to make a mess of it.

It's not hard, I've filled little divots on similar size parts with MIG. Go fast and you need so little heat at the weld that temperatures above even annealing are confined to close to the weld, softening lugs is what you worry about. And if you want you can heat sink there. MIG would work but it leaves more to clean up.
