Well, I think I have my answer. Chrono showed 2840fps for 43 grains. 44 grains gave 2900, but velocity didn't increase for charges of 44.5 and 45 grains. This would indicate that somewhere between 43 an 44 is my limit, I suppose. However, still no pressure signs observed. Kinda disappointed in the meager velocity I'm topping out at. Hopefully, 2800+ is plenty for deer. I was getting over 2800 with 140gr Hornday Am Whitetail factory stuff (though with high SD). In my very short experiment, I'm left with results implying these Barnes boolits are hella sticky!

I'll hunt with the 43-grain load for now, as load-development, range time is waning and I'm zeroed for that load. Maybe, come spring, I can piddle with some 44-grain loads to eek out a few more fps or try some Big Game or CFE-223.
