Ringworm: Whilst doing some research to verify my understanding of the answer to your question I came across information that surprised me and corrected a long time notion I held.
And that was Remington Arms Corporation was NOT the first to commercially produce a factory Rifle in 22-250 - it was Browning Arms Corporation that did so a full two years before Remington (1963)!
Remington did make the cartridge known as the 22-250 Remington proprietery and commericalized it in 1965.
All info I can find leads me to deduce that 22 Varminter dies will reload 22-250 Remington brass for commercial Rifles designated 22-250 Remington.
I say the answer to your inquiry is a tentaive yes.
