No reason on a crimp die why you couldn't do that.
It seems reloaders wake up everyday in a new world. I am the only reloader that has tools designed to shorten a round piece of stock, I do not shorten round pieces of stock but I have three grinders that are designed for that purpose; again I do not use them for that purpose but I have the tools JIC.
And then there is that part reloaders can not keep up with; that would be the big inning, in the big inning there was the 38 Special die set. And then (there is always a 'and then) came the 357 Magnum. Most reloaders purchased 357 Magnum dies because they were not like me; I have threads on my dies and presses meaning all I had to do to seat bullets for the 357 Magnum was to adjust the die to crimp by raising it. And then 'again' die manufacturers figured it out, they made one set to do both cases (the 38 Special and 357 Magnum) by adding a round spacer. The thickness of the round spacer is the difference in length between the two cases.
And then came the 44 Special, and then the 44 Remington Mag, same thing. The manufacturers made two sets of dies before they figured one die set would do both cases.
And then they had to start over when they went to progressive presses because the put the primer punch on the expander die instead of the sizing die and then they had to do it again because the old sizing dies were not threaded for a primer punch.
For those keeping up manufacturers made 5 sets of dies for the 38 Special before they got it so it would work.
Back to my grinders, they will grind angles, they will grind tappers, they will grind to length as in butt grinding and they will grind pilots. My grinders will grind head space gages.
