Hey Hog,
I started loading for a 35 Remington about 45 years ago. I started with a Lyman 2-die set back then, and I am still using the same dies. I always use a round nose bullet because of the tubular magazine, and the bullets I use always have a crimping cannelure. I seat and crimp the bullet in one step. I learned a long time ago how to adjust the die properly so seating and crimping can be done in one step, and done properly. My crimp is a simple roll crimp that only seats the mouth in the cannelure. It does not bite into the jacket and deform the bullet. I wouldn't think of using a Lee FCD when the die I got 45 years ago still works just fine. Whatever grain bullet you choose to use, I would surely recommend a round nose and a crimping cannelure if it is being used in a tubular magazine rifle. I don't like the idea of using a Lee FCD to make my own cannelure by deforming the bullet. If you are not using the cartridges in a tubular magazine, you really don't need any crimp at all.
Best wishes,
Dave Wile
