How to shorten and recrown barrel with hand tool

Although most people are intimidated when it comes to shortening and recrowning a barrel, it's pretty easy when you have the right tools. In this GunTec presentation Larry Potterfield, CEO and Founder of MidwayUSA, demonstrates how to cut and recrown a rifle barrel using an old Winchester model 67. He starts by clamping a Wheeler Engineering dovetail cutting fixture on the barrel at the point where it is to be shortened. A hacksaw is used to cut off the portion of the barrel to be removed and a smooth file is used to true up the surface. The hardened fixture will insure the muzzle is filed down square to the bore. For cutting the crown Larry uses an eleven degree piloted reamer. Chatter marks are removed using abrasive paper backed by his thumb.

Hey MidwayUSA, Great videos. Can you give me the tools I would need to shorten my Mosin Nagant. Besides the hacksaw and sandpaper.

@mikesucho Check out our video "Gunsmith - Shortening the buttstock on a shotgun"; this video will give you an idea of how to shorten a stock to get the right length of pull.

question, in your video you mention using a 11* reamer, a .22 such as the example model 67 is normally lead based, for a rifle such as a mosin nagant shooting FMJ, would 11* be the same? i only ask because i was reading else where that other manufactures use 8* or even 5*. how does this play into the accuracy when being square, round, and true are whats important?

am i over thinking this? i plan on taking off 2 inches to remove the front sight when i add a scope.

@mobapadmin The thing about a crown is consistency. An 11 degree target crown is common in target rifles, and is not really caliber specific. The 5 or 8 would be quicker to cut, and under wartime production demands it makes sense that they would be cranking them out as quickly as possible. Also, they were not really target rifles. More simply put, consistency is the most important factor here. If you have any additional questions give us a call at 800-243-3220. Thanks for your business!

"It all starts with a hacksaw, and ends with abrasive paper, and your thumb.." sounds like every first date ive ever been on.

How would a copper pipe cutter go?

Does this method put small burrs on the rifling at the crown?
