Too cold to shoot, so I re-cut my crown
I need to get some load development done, but I think it'd be time wasted today. It's about 15F and blowing hard.
So I decided I was due to touch up the muzzle crown on my m1A match mule. Pretty easy job--I have the Brownells 12 blade 45 cutter. The hardest part by far was getting the suppressor off. Youtube covers it pretty well. The biggest thing is to clean the cutter and bore between each set so you don't get a chip in there (by chip I mean stuff you can't really see).
Gus Fisher had mentioned they used to do this once or twice a season; just a quick single pass on all the guns to freshen up the crown. I was a little surprised that it took more than a couple turns to get a nice edge all the way around--four or five rounds with the cutter. My two-beer self must have gotten sloppy with the cleaning rod one evening.
Almost 5k on this tube (Kreiger 1:12"); hoping to get it through the season.
