What are you thoughts on using the Lee Factory Crimp Die on rifle rounds for an AR15? Particularly those for 223 Rem and 300 AAC BLK. Is it worth while to use or will it make a difference whether or not I do use it? Or is it even worth crimping rifle rounds at all? I'm loading on an XL650 so it's not a big deal for me to put the extra crimp die in the 5th station or to just leave it out. I'm about to load up some 110 gr Z-max for the Blackout and then some 150 fmjbt and then I may play around with some 208 gr bullets.
