There's absolutely no question that Federal pistol primers are "softer" than CCI.
Whether its an alloy difference or thickness, I can't say.
Federal primers will severely flatten, mushroom and pierce is my G33, with loads from below starting to over max. I tried SP, SP Match and SP Magnum. All do the same thing.
CCI primers, never has a single one done any more than slightly flatten with hot loads.
