It's a BHW Barrel and I added that information in the original post.
I did some case comparisons (water weight in grains) and decided to start a grain below (just to be safe) the top 6 PPC load data and slowly working my way up until I get to 3400-3500 and/or see some type of pressure signs (primer flatting/cratering, swipes, burrs, etc.) with the 58 V-Max, H322 and BR4, Fed 205 and CCI 450 primers. The bullet touches the lands @ 2.245" so will start with a 2.230" C.O.L.
Case Length: Min 1.676" Max 1.686" (Target trim 1.680" + or - .001").
Note: I have about 400 pieces of once fired Hornady 6.8 SPC Brass that was annealed and sized to 6x6.8 SPC in a single step using the CH4D die.

Here's the 6x6.8 SPC with TI Can, Texas Predator Posse Edition Lower with Timney 3lbs trigger and Thermion XP 50 Pro 2-16 Thermal
Waiting on the adjustable gas block and Acra rail but thought I would post how the build is coming.
