It's a LEE die, quite an old I think, one of the old guys at the range gave it to me in a box of bits, press, scale etc...

I rarely crimp on my TC Contender calibers. If I do, it's usually a mild roll crimp. Chambers are different, so play around to see what works best. That's one reason for handloading; I tell my wife it's " hand tailored" ammo and that's why I've got to have so many powders, bullets, primers, hulls, wads, shot, dies, scales, powder drops, case trimmers....you get the idea.
