CH Speed Seater

[xs56gun]

I recently came across a set of 45acp dies and one of them is a CH Speed Seater die.
I'm not really sure what it is, or if I should go with a taper die as well.

Any info on it would be appreciated.
Thanks.

the CH speed seater die was originally designed to facilitate seating of semi wadcutter design bullets in progressive loading machines (believe their AutoChamp and the current 4X pistol chanp) , you would need a taper crimp to remove any expanding you did before seating. I have them for 45 ACP, 9mm, 30 carbine. Believe they ask $40 for a taper crimp die
