Anyone ever use one of those hand reamers? I have done some minor smith work, but was reading that article in American rifleman where he set his own headspace. I just am rather hesitate as I would think it would be so easy to get your chamber out of round with that reamer. I don't have any problems breaking a barrel, but wouldn't mind taking it to a good smith to cut the barrel back. I know some are on here saying, if your going to take to a gunsmith, might as well have him ream it properly.
