390 grain Hornady A-Tip load development 375 Cheytac

I loaded up 5 each of 124 126 and 128 grains of vv n570 in junk Jamison grass; got 2925, 2975ish and 3015 fps with those all with SD less than 7; accuracy was kind of all over the place in a 1-10 twist Lilja barrel, 35"; pockets were loose to start with, starting to get ejector swipes at the 128...

Run the 377gr in a 1-9.
In my experience with 6 lots of H50 charge weights varied from 138.5-142.5gr with one caveat, 40" K&P.
A 400 Lazer is your best bullet for the 375 CT in my experience and a 1-8 spin, best results beyond supersonic. Again, this is with a 40" K&P and with 138.5gr H50.
