300 blk Guys

Hey everybody. Has anyone done any work with 300 blk subs that aren’t as loud and dirty as 1680 or most factory? Been working on getting n105 and 220 grainers. Also awaiting an order of Accura 200 gr plated so we’ll see how those do. I bet those will be easier to get to cycle. Run some of them in my 16” single shot and I’ve heard louder pellet guns. If I open my gas block way up on an Odin works 10.5” they were cycling but made my standard sub loads loud as hell. I plan to update with some specific loads and progress if anyone cares/has done the same.
