How warm is outside temp to make 26 pressure up? 83 sounds low.
Nice group! N570 is great stuff in that size case.Shot my best 100 yard group ever today.
Glad I decided to play with the N570.
Started at 84 grns and worked upto 85.5.
As I increased powder so did the group size.
I had some loaded at 86 and figured I'd shoot them just because. Still wasn't at max pressure.
86 was the magic number.
I'm going to take it out tomorrow and shoot it at longer range and measure drops to determine FPS. Also going to try a little more powder since I'm not quite at max pressure.
