222 mag

Does anyone with experience reloading this round, have data to load 50 & 55’s for the 14” Contender? (I do have Mike Bellm’s Data, but that is for heavier heads. Rifle data will be fine, if that’s available. This case volume is larger than the 223RemAI, so any suggestions on how to modify that...

I have 500 pieces RP 222 Rem mag brass. Brand new never fired. Also have approx 700 pieces with 1 firing on them. Looking to trade for 6.5 x47 lapua 338 edge or 17 Mach iv brass. Also open to cash offers. Thanks,
