[QUOTE="Alan Griffith, post: 677089, member: 4686"] I spent an hour or so at the mouth of Rock Canyon, Provo, Utah, ranging angles up to 32 deg out to the limits of the the ABC Ball Calc. It's a wonderful tool. I would range a rock, tree or bush and write the distance and drop in 1/4 moa clicks. I'd then mark them down in my EXCEL file on my laptop. I go back and immediately range it again but then I'd get the angle in deg, temperature in deg and barometric pressure in inches of MG. I'd then quickly transfer them to my SHOOTER program on my DROID and get the drop, again, in 1/4 moa clicks. My 1600-B was set up in the "1-4" or 1/4 moa mode. I've been running cure #3 with my standard 1600 model and so started with it. These are pretty much level. Curve #3 Yards- Shooter clicks- Leica clicks 138 1 0 149 2 1 156 2 1 230 7 6 256 9 8 303 13 11 413 22 22 440 25 24 470 28 27 472 28 28 520 33 33 531 35 34 553 37 37 693 53 56 725 57 61 802 67 74 841 72 81 852 73 83 873 76 87 These are at an angle.
