Bulk 556 Brass prep and reloading process

[B52U]

Thanks for all the great responses! Looks like I at least need to add a cleaning step first.

I've loaded many thousands of pistol rounds on the XL650 without cleaning primer pockets. I have to be careful with the priming motion, but it saves a lot of handling.

Is priming 556 more difficult or sensitive than priming 9mm?

Regarding priming. Depends on the brass, milsurp/LE brass that has crimped primer pockets must be swaged to remove the crimp material or you will have a bad day priming resulting in mashed/shaved primers. With regular uncrimped 223 brass it's not required. PMC bronze brass usually has nice radiused pockets.
