Brownell's Muzzle crowning

Post by Mt_Medic31 »

Hey all,
Has anyone had any experience with the re-crowning tools on Brownells? I need to touch up/redo my prairie dog gun crown, and being close to hunting season, the gunsmiths are all pretty tied up. I'm not afraid to do it myself, and am considering this tool:

BUT, looks like it's hand turned, and I don't know if I like that or not. I would follow it with a brass lapping tool and polishing compound for sure. Any experience with these or advice appreciated.
DOPE? Boy, do I look like a hippy to you?

Oh, and PS, I don't want to drop the $500 on the Manson precision one. It does look great, but don't want to pay that much.

I have one of those and have used it to good effect. Dont worry about it being turned by hand, you only turn it one revolution while applying some pressure, then clean it up by turning one more turn with very light pressure. Pilot is very precise, no play whatsoever. Money well spent, IMHO .

I have one of the 79 degree cutters that I use to put a target crown on after barrel shortening. They work very well for the money. Here is a photo of my first attempt. This is prior to applying the 45 degree chamfer at the crown.

Excellent info, thanks guys
Trent, looks like a very clean finish, that makes me feel better about the process. thanks.
I ordered it today. I also ordered one of the 45 degree brass lapping bits and 600 grit polishing compound to finish it off. I think it will be money well spent. I will post here when I get it done, and let yall know how it affected accuracy.
