Given the huge variation in the reamer specs for all improved type cartridges I would not be using someone else's data. In additon, even on factory spec rifles we all know there is large variations in the loads they like or will handle.

My suggestion is to start with 222 loads, work up carefully till you get pressure signs. With any improved cartridge, if you get to 200 or 300 FPS over published max for the factory cartridge, you are about max on the improved. Ackley's best improved designs, the 257 Roberts and the 30-30 gained about 2-300 FPS maximium. I doubt you will get that much of an improvement in speed out of a 222 improved. Best of luck.
