Yes, did the chance to shoot (Kind of)

I've been extremely busy this week and didn't load at home, thinking to load over at the ranch. Rushing outr I brought everything, except the press (set up on a portable Sinclair stand)

I had some leftover bullets that I didn't shoot last time due to weird "too fast" readings and setup at at 144yds
For the loads I had speeds were on par of what they should be, progressing from previous. I do believe firmly what I suspected, weird light or chrono not open enough, as has been suggested

65.5 - 3099 3096
66 - 3126, 3124
66.5 - Err2 3111, 3113
67 - 3149, 3149, 3210 (last shot was on a hotter chamber than planned)

Shot round robin and POI fairly same for all of them, but I decided to change rear bags halfway through (dumb!!), so POI shifted between 1st and 2nd shot of same charges (but almost same for each string of different charges)
I got some minor primer flow on the 67gr loads. No extractor marks or hard bolt lift, but I would call 67 max, and will try some groups with 65 - 66.5 range and see if there is one that shines clearly over the others
