So the other week, I had mentioned that I had loaded up all my brass with 107 SMK HPBT with 26.8gr of Varget, CCI 400s, out of a 26" 1:7, bolt action rig. I just needed a load that worked, since I didn't have enough time to do a proper load/ladder work up before going sage rat/ground squirrel hunting in Eastern Oregon. Used all my loads, no pressure issues, but precision wasn't there obviously.
In searching through other threads, Lever Revolution is very popular here, so that is first suggestions, but I don't have any. Also, when people were disassembling the Hornady Black, it was compressed and found to be 32gr of spherical powder, assumption being CFE223. In running the loads through GRT, my guess is that they are using Superperformance, and the 32gr powder is right at the top of the pressure curve.
So, what I'm thinking is to get some Hornady 105gr HPBT and work up a load with the SuperPerformance and see if I can match what the Black ammo did for me, 2760 FPS and less than an inch at 100.
Yes, I know this powder is a lot slower burning than Lever and CFE223, but I also have a lot longer barrel than most.
Any other thoughts?
