After accumulating 12 54R cases and some .311 bullets, I decided to make 5 test rounds. Started off by replacing the .308 expander with one from .303 British dies, just like Lee says to do, smashed two cases. Crap. No biggie, adjust the expander, size the other 10. Cleaned up the cases, primed 5, charged them, seated bullets. No neck tension. Seated a little past the cannelure, no dice. Go to pull the bullet, grabbed my .358 collet instead of the .308, scored another case. Now I'm at 9.
Decided to try the .308 expander, bullet goes in with to much tension. Neck bulges. Put the .303 expander back in, smash another case. That leaves 8, and a very agitated person.
What's going on with this neck tension issue? I don't believe it's the brass. Could be the short 123 gr bullet. Could be I need a .310 expander. Don't know. I do know that I can't find more 54R brass at an affordable price! Think its time to try and shave .001 off the expander? Not really sure that's my cup of tea.
