I don't know if anyone said this or not, check your owners manual, my colt m4 22 has a bolt in the rear or the upper receiver, I was shooting centrion target ammo through it and it jammed I adjusted the bolt accordionaly and it didn't jam as much I think it was 1 in every 60 rounds it did the same thing through the ruger 10/22 so I assume the rest was just the ammo.
