All brass looks excellent, and groups are pretty good also. Shot in order NOT round robin. Thinking 42.3-42.9 is a node based on nearly identical POI. Also looks like 43.2-43.5+ could be another node. Was hoping to see 2800+, will it get faster now that the brass is fired? Do I dare go higher than 43.5?

Never really done an OCW, always just loaded 5 of each and shot them, best group i loaded more and if they still grouped good, that was my load. Not sure how to proceed without wasting barrel life.
