I use the dillon dyes, but I only reload 45 acp and 10 mm.
All of my brass is either win, rem of starline. I'd say about 75% win, 15% rem and starline 10%
I only reload brass a few times, then I scrap it. yeah I know I could get more out of it, I just choose not too.
45 acp brass is easy to find. 10 mm is harder, but still easy to find.
I don't reload 38 super, I should, but now that every one locally has moved on to 40 to make major, once fired 38 super is hard to find.
