Re-crowning an M1 Garand

My Winchester Garand had a muzzle erosion of 3 and had a very beat up crown. I ordered I re-crowning tool from midway to try and clean it up a bit.

The first challenge was trying to find a tool that could take a 1/2″ bit. After a tour of several hardware stores I gave up and borrowed an old hand drill which fit.


I put a little bit of light oil (left over hone oil) on the bit and shaved the crown down a bit.

I am pleased with the results the crown looks nice. I may have take more off the end than I probably should have.


Post re-crowning the muzzle erosion has improved to around 2.25 if that improves accuracy or not I will find out on the next trip to the range.
