Right now I have 42.8 grains of H4831SC under 105 Amax in once fired Remington brass at 2.775 OAL. Under 1/2 MOA. Not done tinkering and I have not shot groups past 400 yet. Doing that today. I also have 115 DTACS loaded for today and I will see what happens past 400.

I full length sized RP brass and nothing else. With the 105s, that worked fine. For the 115s, I had to chamfer to keep from peeling the jacket. I am doing a few things different with this that I normally would.
