7x57 and 7x57R . . . same dies?

If I had a 7x57 Rimmed chamber cut for my Encore, could I still use my 7x57 dies, or would I need to get dies specific for the 7x57R?

Obviously, if I went 7x57R Ackley Improved, I'll need new dies . . .

Same dies, different shellholder

The "R" versions of the 57mm, 60mm, and 65mm Mauser-head size cases use the RCBS #26 or equivalent shellholder.

Maybe not. I do not have any experience with these two cartridges, but the drawings in Howell show enough differences to make it possible that one would not fit the other. There are diameter differences in the base, the shoulder, and length differences in the case length, the length to shoulder, the length to neck, and in the shoulder angle.
