So I have this 617-6 10 shoot that will rarely fire a complete cylinder full. What seems to happen is that upon firing a round some of the rounds unseat from the cylinder under recoil. Does anybody have experience with this phenomenon? If so what was the fix. I have not gone to the trouble to identify the guilty charge holes yet, but it usually happens like this. Fires,No, F, No, f,f,f,f,no, Fire. My theory is that some of the charge holes are slightly oversized.
