Help! crown damage
« on: May 29, 2007, 03:18:59 PM »
In a fit of stupid(without a muzzle guard), I let my cleaning rod slip and nicked the crown on my brand new Beretta U22 Neos with a stainless steel barrel.  With a good magnifying glass I can see a small nick right on the edge of the crown, looks rolled up a little.

Is there any hope such as a slight counter bore with home equipment, or must I have it recrowned by a gunsmith?  The nick is very small and the pistol seemed to shoot fairly well, but it might have done better without the nick.

Really didn't want to spend extra on a new pistol.


Thanks for any help and advice.

If it shoots well don't worry about it.  If it doesn't you know where to start.

Keith offers good adivce, it may not affect it.

I've done a bunch of touch ups, if it doesn't help, see your smith, mine have always worked tho. Sometimes, just a steel ball bearing and some valve grinding compound is all it takes to smooth it up. I've  also used the method below on a couple barrels that I cut off.

Remember the crown is not the whole end of the barrel, just the very terminus of the lands and grooves, the end of the bore..as it were. Any damage that can be seen on these areas can produce problems. A dent in the metal that makes up the rest is simply unsightly.. A really good suggestion has already been made. Shoot it and see if there's any change??

Valve grinding compound on a 45 deg. brass lap turned slowly in a drill will clean it up. If you don't know any machinists to make you one, Brownells sells them. The lapping compound does the work not the brass. Use very little pressure and take your time. It'll work fine. I use 500 grit with mine.
