The fact that it ran the Federal hollow points tells me the other practice stuff might not have enough horsepower to cycle things as they should.
Given more rounds it should cycle those just fine and dandy but for now it's balking on ya.
I don't know what practice ammo is the hottest but Kahrs like full power stuff especially at first.
