Good work, your on your way.  Check out some of the tuning guides for the impact / Crown here in the forum. It’s a true balance you need to find. On one hand you want to tune all the aspects of the rifle for max efficiency. Most of the time those tuning values will lend themselves to the best chance at accuracy, but not always. Once you find the “harmony” of the gun like Ted likes to say, fine tune your velocity for the best accuracy and pellet your running. From the looks of our groups, those are good for sure but not even close to what I’ve personally experienced and seen the crown capable of.  When you get it dialed in, you should be able to put together a 5-shot group under .5” at 50 in good conditions prettt easily. To me, 830 seems a bit slow for the smooth twist and 18.1’s.  I would start there and slowly go up until you see your groups hopefully tighten up. Pick a good morning or evening with no wind and go to town.  Good work, your definitely on the right track.
