I previously loaded a 165 grain Ballistic Tip Nosler over 42.0 grains for .308. I was taking a stab at two different loads as I had only 8 bullets left and was going to the range anyway. Well needless to say the load shot about 2". So today I got some more 165's (same bullet) from Cabelaclause and loaded a 20 shot test group in 4 shot increments from 42.0 down to 40.0 in half grain increments. I was using the 42.0 as a reference that it was not good in my gun, but to be sure I ended the testing at that number. Well, to my surprise all of my gropus sucked except the 42.0! It was about .55" group! I feel as though I shot pretty consistently each time, and everything else was the same. Even the temp was close. What could this be? I am thinking an inconsistency in sizing as I have not yet found a sweet spot to the full length sizer. No matter where I set it they chanmber hard...What gives?
