Now you've got me wondering.... I JUST shot my 450 build the other day and had to single load due to not having the proper mags yet, but it did shoot ok. I've heard of bullets creeping a little in the brass due to recoil, which will change their OAL which in turn could have an effect on accuracy, but that would probably be on a case by case basis. A sturdy crimp i would think could mitigate that.
