Quoted: What is the best 6.8 load and twist rate for that monster?
How about a 6.8 forums group trip??????? |
Hmmmm, excellent question, my friend,
I will better be able to answer that once we have tested the 1 in 12 and 13" 3 groove barrels at the next test. I fully expect to be able to drive a Barnes TTSX to 2800, maybe even 2850, in my 20" 12 twist, 3 groove, stainless Pac-Nor, which is "in the womb," so to speak... I think you could also get away with the Sierra Pro hunter 110, using 31.5 grains of H322, or a SSA combat Pro Hunter.
Even my Cardinal armory 16" LW , 11 twist, 4 groove made 2700 FPS with the TTSX and 29.5 grains of RE 10X. That showed no siginficant pressure signs, so there might even be just a little more there, but I thought it brash to tempt fate and push the load farther than that, especially when that grouped 0.63" !
