Muzzle of shotgun question

[JBeardNC]

I'm refinishing a CVA double barrel 12 gauge and I had to clean up the muzzles with a file.There were still a lot of machining marks on them. It left the crowns with very sharp edges. Does a thin shotgun barrel need a crown at the muzzle or should I just radius the edges over? Unrelated, but I was surprised to find that the case hardening on the tang is real and not chemically applied. Thanks for any tips.

In my opinion it won't hurt anything to round the edges - al least a bit. You don't want to slice wads or cartridge paper when loading.

Or fingers...

Thank you, that's what I was thinking as well, but was unsure.

All you will need is just a piece of emery cloth and you thumb to break the sharp edge. Just put the emery cloth over the muzzle and rub it around with a circular motion with your thumb.

If you have a screwhead that is larger than your bore, chuck the screw into a drill , then put a small piece of emery paper on your muzzle. Slowly turn the drill until all inner edges of the muzzle are smoothed.

Thanks guys, I had forgotten about using a brass bolt to crown one.

For a 12 gauge that will be one big bolt made of brass to find not to mention expensive.

I have a brass tool made in my shop from a 1" round of brass, angled the front no idea the degree and turned a 3/8" shaft at the other end. Grinding compounded the front and turned it with a drill into the muzzle. It still needed some sandpaper on a thumb to make it nice and smooth entry for wads.

I will shoot a pic of it when I find it.

Thumbs are cheap, and you have two!
