[QUOTE="Fiftydriver, post: 222198, member: 10"] From 2500-2800 fps 0.770 is about perfect at my elevation. At 2900-3100 fps I have found that 0.790 is perfect. At 3300-3500 fps, I have used 0.800 to 0.820 depending on rifle. These are all out of 1-10 barrels of different chamberings for the various velocity ranges. For an all around average I always use 0.800 and that will get you extremely close with any velocity out to 1K so you can tweak your drops from there. [/QUOTE]
