I wouldn't do this to every shell holder/die set up, this one just needed a little taken off.
I see you are in Michigan, so am I. You might want to stop by the shop sometime and I'll show you a much easier way to fixture the shellholders or a die for that matter. I'm real close to Cabelas in Dundee, like 2 miles.
The inherent issue is they are cylindrical so 'clamping them in a mill vise' only imparts clamp forces on a very small part of the circumference, so things can get, shall we say, loosey goosey real quick.
Much better to clamp as much of the diameter as possible and using the registration surface (lower side) of the shell holder to square it in relationship to the cutting/grinding operation.
I should go into business grinding shell holders and dies....lol I'm already in business. Firearms are a hobby.
