I recently decided to start loading .223 Rem. I already had primers, and I found powder and bullets pretty cheap. I also have a bucket of brass from years past, mostly Federal, that I decided to start with. What nobody ever told me was that Federal .223 has crimped primers just like 5.56mm. So, I had a bucket of brass I couldn’t reload. I then had to order a primer pocket swager so I could put primers in these things. Anybody know of other brands of .223 brass that has crimped primers?
