nrl 6.5 creed berger 140 hybrid and 4350

Looks like you will make power factor easily. When I used to shoot 140's I always always around 2750 which makes it by 30 FPS but it always worried me that you could be shooting slower for some reason one day and be on the edge. The easy way to make power factor and not have to step on pressure is usually a heavier bullet - 147 eldm, 153 a-tip, 153,5 berger, 156 berger.
Those 150 class show as not fully stable in 8 twist for some of us low landers.

144s worked well for me at around 2675 in a 24” ctr. 42.0 h4350 in LRP Lapua.

That is true. I am shooting 153.5's at 2615 FPS in a 1/8 twist but I am usually shooting around 3,000 feet elevation.
 
Hey Frankie,, wanted to follow up with you. Curios if you were able to find and hold accuracy with fired brass? Mine is basically the same as yours, shot the same level as yours did, then opened up after reloading. Your experience?
Yes but i noticed i had to adjust my seating die with fired brass to get the same btog measurement. Powder charge ended up being the same
