For 9mm I buy the Winchester Valu Box and use the Winchester brass. It is only a couple of cents more per case than the Starline. For .38 sp I buy Master ammuniton (wadcutters) again for the Winchester brass- about 3 cents more expensive than the Starline cases. For .357, 10mm and .45 ACP I buy Starline. I have noticed there is quite a spread in the Starline lengths and virtually all are shorter than the trim length listed in my reloading manuals. When I buy an order (500) I resize, measure and sort by size and use the groups of cases that will get me a good balance between using the most cases in the order and trimming as close as possible to the correct trim length. The ones that are TOO too short go into a "mixed range brass" coffee can I keep for plinking ammo. When I load my practice ammo, I try to load a box or two that I put back for la revolucion, so I want them to be uniform (identical) in trim, crimp, load (I measure each charge). They go into ammo cans with dissicant stored in a spare closet. I hope to join an IDPA group in the near future, and the "mixed range brass" will be used for that.
I'm not reloading for .223 yet, but I'm saving my Black Hills reman cases- just deprimed and cleaned two boxes this afternoon. That's about all the commercial .223 I shoot- I was shooting some XM193 from time to time but am hoarding that until I can figure out if it will become economically available again. brassman.com is another source for Lake City brass.
