Redding Profile crimp die?

[Shrinkmd]

I am confused, I am looking at their online catalog and Midwayusa, and it looks like there is a 38special/357 Profile crimp die as well as a 357 only. The 357 only is a special order, and the 38/357 is in stock.

What is the difference between these two dies? Why would Redding make one which is dedicated to 357 only, when the other can do both?

My other question is, do people find a big difference in doing the seating and crimping in 2 separate stages? I know for semi auto rounds the sentiment appears to be do it separately. Does this hold as true for revolver rounds needing a roll crimp? I do have an empty 5th spot on the press if I want to do so.

Is the Redding crimp die the best for making uniform roll crimps?

You have more control over the bullet seating and crimping operations if you do them separately.

The Profile Crimp die is an excellent crimp die.

The profile die will not seat the bullet requiring the seperate operation.Standard die will seat and crimp in one operation.
If you are going to seat and crimp in one op you best have trim length exact and know how to adjust the die.
Any roll crimp die will do you a good job.

edited to say trim length needs to be uniform for that setting
