I am a proud first-time gun owner with the recent purchase of a Mosin Nagant 91/59. The gun is in excellent condition and the seller was very helpful (GunBroker transaction; the guy who sold it me checked the headspace and firing pin protrusion and is machining me a no-go headspace gauge for free). But, the crown of the gun got damaged in shipping!

I have called around to local gunsmiths and most of them don't want to deal with it and the others want $70-$150. I have access to a good machine shop with lathes and so I was thinking of tackling this myself and am looking for advice.

With respect to the inside of the bore, I have seen videos like this one by Larry Potterfield on how to clean things up. What I am unsure about is how to deal with the gouge in the chamfer. Would I need something like this chamfer cutter on Brownells? I guess one option would be to simply cut the barrel back a bit and leave it with a flat crown, but I'd like to change the rifle's character as little as possible.

So, if any of you can recommend a good gunsmith in the Boulder area, please let me know! And, if you have some advice on how I can go about doing this myself, I'd love to hear that too. Thanks in advance
