I'm loading 9 major. I fill a 50 round .45 plastic ammo carrier with 50 pieces of mouth up range brass. The next step is to use a high intensity light to shine down each case to look for the step that is in IMT, AMMOLOAD, and FM brass. One case separation is quite enough, thanks.
BTW if you have a 1050, any of that that step brass crapola that sneaks through will reveal itself in the swage stage by the feedback to your pull.
