Hi Laker, I built a 6.5 Sherman using a 700 action, CF Proof Sendero Light, AG CF stock and Timney HIT trigger. I have 50 cases fire formed of Winchester brass and ready to start load development with the 156 which is what I built it to shoot. I have H1000 and multiple flavors of primers both LR anf LR mag. Would you mind sharing what you saw when you worked with H1000 ?H1000 goes 3100fps
