Thread: tidy up crown on .22lr

Funnily enough I was picking up some supplies on Sunday to do this very thing, had a hand me down .22 semi with a bulge and a ring in the barrel. Hacksawed the barrel after work yesterday, filed flat, evened out with reducing grades of abrasive paper, rounded off the edges, then did the brass round head thing. Tested this evening and groups super tight at 25m, will check on the weekend at 100m. Could be tidied up a little bit, but as long as it groups well at a hundy will leave it at that and cold blue it
