Just wanted to provide an update. Been playing around with seating depth to try and squeeze a bit more accuracy out of these bullets. Moving from an CBTO: of 1.895\” to a 1.885\” using a Hornady Bullet Comparator Ive been able to shink my group sizes down from an average of ⅞\” to an average of just over ⅝\” in the .68\” – .72\” range.
I also dropped my power charge from 26.5gr CFE223 to 26.2 and still yield the same MV from my 18\” Criterion Core Barrel. Still using a Caldwell Lead Sled and 10 shot groupings.
Im sure Im limited by my Nightforce 1-8 LPVO at this point. Will try using a higher magnification scope that has parallax adjustment when I finally get one.
