I nlknowvSmall rifle primers are hard to find.
How about .223 brass?
Curious as I saw 100rnd "cannon blank" packs for $44 made from 5.56 brass.
Was thinking about either Dumping powder & trimming the cramped necks or firing, sizing and trimming..
Considering 223 new brass is ~$32/50 it seems reasonable...
All of my 223 rem brass has been free. I find it laying all over the place...
