[QUOTE="Jumpalot, post: 813360, member: 4867"] I've recently started working with this this bullet and powder as well with Norma brass and Fed 215 primer but in a 26" barrel. I started seeing pressure at 77 grains. Went out to shoot groups with 74, 75 and 76 grains. I "guessed" my velocity at 2900 fps to enter into my Shooter Program. Set up a target at 725 yds. and shot groups. The 74 and 76 grain loads were right at MOA. The 75 grain load was slightly better but showed some vertical dispersion. Loaded up some more at 75 grains but pulled my expander ball out of my sizing die to increase the neck tension a little and went out and set target at 725 yds again. Shot some groups and was right at 1/2 MOA. Had to adjust my velocity to 2925 to get it to match my drops. I used to do a lot of shooting over a chrono but found out that they were only good for a starting point for velocity. Still had to shoot at distances to verify drops. I will get out to shoot at 1000 yds this weekend. IMHO, there is no substitute for shooting at distance to verify drops. In your case, I would carefully start working towards some higher loads to see where you get pressure. For me, my accuracy loads are usually 2 grains less then where pressure starts. Good luck and keep us posted. [/QUOTE]
