You know, I am going to assume the die set I use (Dillon # 14400) is an "Accu-crimp" only because the Dillon folks (on their web site...link below)
suggest you will get a taper crimp die if the caliber is considered a semi-auto. I would think 38/357 caliber dies would be considered a revolver caliber.
The die gives no clue, nor does the box. I own three sets of Dillon dies chambered in 38/357 and all say 14400 on the box.

Thanks, it's hard to screw up when you use a Dillon 650...it's a great press.
