I use RCBS dies with a Dillon 550. I would think however, that a fairly significant weight difference and the shape difference would lead to different oal. Also, with a 200 grain swc (H & G 68 or similar), I use an oal of 1.260".
I would suggest that you make up a dummy round with each bullet seated to whatever oal you want. When you change bullets, readjust your seating die as required.
