Took my Rattler out today, and it ran just fine with supersonic rounds, but was a bit less so with unsuppressed subsonic rounds. I left the gas full open and it just wouldn't run consistently with 220gr Remington, not enough gas to strip the next round. I knew this could be an issue, so I'm not upset, but I'm wondering if anyone has had experience with different subsonic ammo that cycles consistently in the Rattler. I was thinking maybe the Gemtech 208gr or some of the 194gr might work. Supersonics work both suppressed and unsuppressed. Would love any thoughts. Thanks
