22 Cheetah forming procedure

I bought a Remington 700 today chambered in 22 Cheetah with the 40 degree shoulder. The rifle came with a Neil Jones forming die, decapping pin with four bushings and no instructions. I also obtained 500 URBR 308 cases with the small rifle primer. This rifle has been fired 30 times and prints one hole groups at 100 yards. On a reworked 40X stock, it's really a nice piece.
Has anyone out there performed this procedure and if you have, could you give me a clue on how to adjust the die to start forming. Before I form any of the BR brass, I will be using Winchester 308 brass as practice so I do not ruin any of the BR cases.
