45 Colt max case length is 1.285
45 ACP max case length is 0.898
The difference is .387
Would using a 45 ACP taper crimp die work to apply a tapper crimp to a 45 Colt case if I keep the die body raised up off the shell holder a minimum of .387 which would probably be the maximum amount of crimp. Raised up more, say .407 and slowly move it down to the desired amount of crimp as measured across the case mouth with calipers.
Would this work?
I dont want to buy a 45 Colt taper crimp die just to test a few dozen cartridges.
If the test works and Flat nose plated 45 ACP bullets work in my Win M73 and revolvers I would buy the proper length taper crimp die for 45 Colt.
