Bearrr264,
Thanks for the followup. I was guessing a much larger head diameter.
I'm curious how you swedge ~.03" from the head of any rifle case using normal size dies (eg, 307 to 303). I take it that you use a RCBS Rockchucker, or similar maximum duty press? I thought I would spring the frame on my Jr, so I stopped. Multiple die brands, polished dies, different lubes and lube quantity, case annealing; at best I ripped rims off trying to extract the cases...
