The ones I had were taper crimp, and yes for those.Other than the carbide ring does it put the same crimp as the seater / crimp die does that comes in their 3 die sets ?
One positive thing about their crimp is the crimp is not cut into the die body like most, but into an insert which screws in and has an o-ring, so it has some give. I would think this would help when case length varies a little (a little), and maybe help center the insert and crimp more evenly around the case.
Dunno, but it makes sense to me
