[QUOTE="SHRTSHTR, post: 423591, member: 12514"] Phorwath, Thanks for the kind words. I was happy with my vertical dispersion and both my 800-1000 yard groups were under 1/2 moa center to center. I am a little confused as to why I am shooting 5 inches high. My muzzle velocity is 2933 fps and I am using a G7 of .381 for my 300gn smk's. Changed my velocitity up to 2975fps and all my drops worked out perfectly for 500, 800 & 1000 yards. I do not believe I am doing this right. It is hard to believe that my Oehler is off over 40 fps. I think my velocities are correct and maybe I need to try changing my drag coefficient or BC? Would like to hear what LB users have to say. I could also just reset my NF turret 1/2 moa low at 300 yards and my dialups would be good to 1k. I plan on shooting further sometime this week. [/QUOTE]
