Hello, new here. I have a Remington 350Mag 700 Classic (old style) coming, and I plan on ordering a Lee FCD when I get my brass/loading dies ( forget finding factory ammo,ha) I was wondering if I can use the roll crimp of the seating die, although lightly of course, on a bullet w/o a cannelure? (What I like about the FCD the most) I will be Ok on the Remington 200 corlokts crimp groove/overal length. I just don't want any bullet set back as I want to work up loads asap, and it takes Lee a few weeks to make the custom FCD. I am looking at COL of 2.80 or so as the optimum with the longer bullets of 220 and up. Any help is appreciated. (BTW I am "jazzed" about the Classic! Love them)
