Brownells sells a muzzle chamfer kit to recrown your own rifle if needed. Seems pretty easy to do. Did anyone out there recrown their muzzle with this tool.
If you are not careful you can get massive amounts of chatter using this tool. Sometimes if you are careful you can still get chatter. Once its there it is hard to remove with the tool. That and you are limited to the pilot bushings they send you. I would (and have) crown things like .22s with their tool, but anything else and I would use a lathe.

This is all true, you gotta develope a feel for it. I've been using these tools for 15 years now. 11, 45, and 90 degree. They work great for me. Use lots of Do-Drill. The 45 degree brass lap has been helpful too.
I've had to recrown three of my rifles with the 11 degree tool sold by Brownell's. It was simple to do and cut my MOA groups in half (bad crown on a new Howa 30-06, damaged crown on Rem. 700 270 Winchester, Winchester 94 30/30). I don't have access to a lathe but had no real problems making the tool work. Good luck.
If you want a nice 11degree target crown, there are tools available for that, but if you're the frugal sort like I am, I already own a brass screw and grinding compound.
I didn't have any trouble with it. Make sure you clamp the barrel securely, and use plenty of oil, but I've re-crowned 3 rifles so far without any hint of chatter.
I did also buy the 1/2 hand drill adapter, and the brass guide rod. I did the whole thing in my wood shop in about 10min.
All in all it came to under $100 which I felt was a pretty good deal as it's less than it would have cost me to have one of them done by a smith.
