Re: Wilson 50 BMG Case Trimmer Work On .22?
I've never seen the Wilson 50 cal case trimmer, but use the other one.
Taking the actual cutter and looking it over in good light, you will notice in the area where the cutting edges come together. This area is known as the "web" of the cutter (imagine there are other names as well). The web dosn't cut as well as the outer edges, and this is also where max tool pressure builds up the quickest. The cutter is basicly a four flute end mill. If a person knows their trade well, they can relieve the web to where it's nearly gone (I think you could get it down to .150"). The trick with the Wilson cutter is in the grind. They do a generic style of cut, and your cutting brass. Not so good, and this leaves a bigger burr plus needs a little more tool pressure. If you resharpen the cutter, be sure to tell them your cutting brass (or better yet bronze). The only serious difference is the angle of the reliefe on the cutting edge. Needs to be about double what Wilson uses. This is when you recut the web to make it narrower, but it also is best done with a "web grinder". Still I've actually seen old men do it by hand ( I never was that good). But for very small case neck diameters, a two flute cutter would be better. There is virtually no web to worry about.
