Put together a new load of 50gr VMax, 24.0 gr Xterminator. Need to test it out so this challenge seems like a good fit.
You could work that up a bit. X-Terminator always gives me the best accuracy pushed to max. In a 5.56 chamber you can take that load at least 2 grains higher.
I'm hoping to get to the range this weekend, to shoot one of these targets.
I don't doubt it.
I was running 25.0 gr XTerm under the 50 VMax and accuracy was about 1 moa in the Ruger American Predator, and about 1.5-2.0 moa in the AR-15.
I was hoping that dropping pressure a bit might tighten it up, but we'll see. You may well be right in that 26.0+ might be the sweet spot.
