Mac 10 .45

I have the opportunity to shoot a friends new Mac 10 in .45 this weekend (select fire). Rather than use his ammo I was going to load 250 230 grain/800 FPS rounds. I have no way to crimp the primers in place and I assume that this isn't a problem.

Is is necessary to crimp the primers for full auto handloads? (not sure how I would accomplish that but I'm sure there is a way)

My normal load has a slight taper crimp on the bullet. Do I need to put a heavier taper crimp for full auto?

I have never fired or loaded for a weapon that was full auto before and I'd just like to be sure.
