Thanks everyone for your suggestions. I have on hand 50-90, 50-70 Sharps, and .500 BPE 3" and 3 1/4".

I contacted RCBS, will not make a set. CH4D not in stock and 1 year wait time. I am waiting for
replies from Redding and Lee.

I have found a custom die make that only needs 1 fired case and 14 weeks delivery time, so this is
my last resort.
