Gunsmith - Crowning the muzzle of a rifle barrel

This GunTec video provides the information necessary for anyone to recrown the muzzle of their rifle using simple hand tools. Larry Potterfield, CEO and Founder of MidwayUSA, repairs and crowns the muzzle of a Winchester model 60 to demonstrate the process. Start by removing all of the damaged material from the muzzle with a smooth, chalked file. Tool marks are eliminated by polishing with varying grits of sandpaper, using the file as a backer. Once the surface is square and smooth, the crown is cut using a round headed, brass wood screw and a bit of lapping compound. Simply apply the compound to the head of the screw, chuck the screw in a hand drill, and touch the head of the screw to the muzzle while turning it at a medium speed.

could I still use a brass screw to crown a chrome lined barrel? or should i use a stainless screw?

[MidwayUSA]

@TheKLYPH The purpose of the brass screw, with the lapping compound, is to take the burr off the end of the rifling. We would not advise the use of a stainless screw.

Thanks for Your Business!

Guys I am a certified master gunsmith. Take it from me thats not how its done. In order to recrown a muzzle, you have to strip the reciever of all parts. Then chuck it up in a 3 or 4 jaw lathe chuck about 3 inches from the muzzle tip. Then you'll need to get you a piece of high speed steel tooling and grind you a 22cal crowning tool. A lathe is the only way to be 100 percent sure the crown is perfect. If its not perfect it will send the bullet off coarse

@GunsmithMMG yeah I would have put it in a lathe and faced the end a few thousands and then put a small chamfer on the inside edge and i'm just labeled as a welder...lol

I like the older video, Larry comes off more genuine and a little less rehearsed.

[MrDip02]

@GunsmithMMG he already has vidoes of him crowning the muzzle not REcrowning them -_-

[Nwest82]

@GunsmithMMG I guess this would be better described as "touching-up the crown"

[aboody006]
