Unless I am sure they are done, I just swage them all.View attachment 42456 I found all my stuff really quickly so I got my test fit(two cases; only two in case I trashed them 'cause it seems too easy!)after all, it's LC brass.
I had swaged two cases so I primed two cases: effortless. Next, to make sure I wasn't swaging needlessly I tried to prime another: no go. This was done on a Lee cast oring SS press with the little arm that fits inside the ram.
There is a huge difference between the 223 mil cases and the 308 mil cases. The 223 ring is very obvious but the 308 is very faint so I was unsure if I was swaging enough but it's hard to overdo it with this set up.
I'm not sure if I'm on track here, but I got an RCBS small swager from Dawico a while back - primarily for .223's and I love it. Prepping rifle brass is a PITA regardless, but just doing it and not having to worry about primers seating correctly is well worth it.
