Don: Use the FL die to push the shoulder back enough to close the bolt. Do it by trial and error adjusting the die down just a tiny bit each time 'til the bolt closes, maybe with just a little resistance. You'll end up with a shoulder that has a slightly rounded look, the bottom half will be making contact with your chamber wall, and the top half will be blown forward fully on the first firing. That's all there is to forming the 220 Russian case to your 22ppc chamber. I believe the Russian case is a 28 degree shoulder angle, the ppc is 30.
You will probably want to run an expander into the case necks, with just a little lube on the inside, to open them up. They are usually a little too tight if not expanded. I use Imperial Die Wax and wipe it off with a cotton q-tip before bullet seating.
Case mouths should be deburred and I use the KM inside taper neck reamer to cut a nice smooth entry angle for the flat base bullets, 52 gr. Berger #22408.
Primer pockets could be uniformed if you use the dedicated Sinclair BR/ppc uniformer. Some believe it's necessary, others do not, your choice.
Loaded cartridge overall length will depend on your throat length or freebore dimension. It's up to you to determine what bullet seating length is required to touch the lands, .010" off, .020" off, etc. For that I use the Hornady chamber O.A.L. gauge, and seat them to touch.
About the only consideration left is chamber neck diameter, whether it's a no-turn or tight fitted neck that will require outside neck turning. My chamber is .251" requiring that I turn case neck walls to .012". That is of course done anytime before loading/ bullet seating.
Knew I forgot something: overall case length. Should be O.K. as is but unless you have a reamer print drawing to show that length, or you take a measurement of your chamber with the $7.95 Sinclair gauge, again, before loading try to chamber an empty case. If the cases are too long, the bolt would not close, but this would not likely be a problem with new brass. In the future, with repeated firings it would be a concern.
