Yup, I've cleaned the magazines. I've disassembled the 22 bolt and cleaned every piece of it. The gun is as clean and oiled as possible. It is feeding 100% reliably and functions 100% in semi-auto. I'm only getting the issue in full auto. Update after the last range day: CCI mini-mag ammo failed 8 out of 20 rounds and remington thunderbolt only failed 1 out of 10 rounds. I'm thinking the sear release is getting tripped too early allowing the hammer to follow the bolt without enough force? Starting to think something in my trigger pack is causing it.
