I shot some more with the 168's, shot a 10 shot group, 8 in a solid 1/2", one shot out of position opening it up and one pulled. Ended at probably 1.1"
Another 5 shot that was probably .75"

I'm still very much the limiting factor, I'll post the groups, the 10 shot makes that very evident, but for now I have a match to get ready for.

The 175's are the winners here, I'll order two more cases this week.
