What crimp die does everyone use for 45acp in a revolver?
The crimp depends entirely on the bullet being used , when it comes to revolver ammo .
If the bullet has a cannelure or a dedicated crimp groove ...
... it gets a gentle roll crimp.
If the bullet is smooth sided ... no cannelure & no crimp groove...
... it gets a taper crimp
Now that doesn't mean you can't simply taper crimp them all ...
You can Taper Crimp any / all bullets ... But (there's always a But ) ... in a revolver the unfired bullets in the cylinder want to creep forward when shooting , the recoil pulls at them ... check your unfired rounds as you shoot and make sure you have enough taper crimp to keep the bullets from "creeping" forward . If they do ... add More Cowbell ... I mean add More Crimp ... (I watch too much old TV - SNL ) .
If you have standard 45 acp die set it will usually have a taper crimp die ... but a roll crimp die is sold / provided with a set of 45 Auto Rim for us revolver guys .
Usually the taper crimp die can be adjusted to hold all but the heaviest bullets with the heaviest loads ... when you get to the heavy weights , usually revolver bullets, you may need to go roll crimp .
Let me add ... In a revolver you can go with lighter loads ...
loads that don't function a 1911 action are just Jim Dandy out of a revolver ... try 3.5 grs of Bullseye with a 200 gr. cast lead SWC ... just don't load them into your stock 1911 ... they may not cycle 100% !
