Sometimes crimping can be done with the seating die- with some makes/models of dies. I can't begin to help you with your endeavor to crimp, as I don't crimp any rifle rounds. Is crimping not covered in the instructions and/or other paperwork that came with the dies?
Also, someone here will likely have your brand of dies here themselves and will likely aske what brand of dies you have.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
