Also I've been reloading .223 mainly and I'm going to start 9mm and .40 and .45 on a dillon progressive. Is it a good idea to sort the cases by manufacturer or might I be fine with dumping them all in a 5gal bucket? I'll use carbide dies of course.
Since the red-stuff part was answered, figured I'd reply to this one... I'd just dump em in the bucket.
I sorted by headstamp when I first started... but quickly gave up once I realized it offered no benefit.
The only plus-side to sorting by headstamp, would be the extra scrutiny you'd give the cases in regards to culling out any undesirables. Such as AMERC cases, any steel cases that slip past you, any military brass that might be crimped, and for the 45ACP cases... any random cases with a SPP instead of a LPP.
For random range-pickup brass... I still go thru the motion as if I'm sorting by headstamp, to cull out any of the above. But instead of 15 different piles... just have 2... keep, and toss.
