Yes, I ordered some Jamison .25-20SS brass and will form into R-2 cases, anneal, and fireform into Max Lovells. I found that I can neck size with a .222 Remington die, and seat with a .22 Vickerman Universal straight line seater. Half baked way of doing it, but at least I'll be able to determine accuracy potential before springing for a set of Maximum Lovell dies.
