[QUOTE="Mike6158, post: 573646, member: 1039"] Well... I went to Berger's site and downloaded their ballistic program. I plugged all of the data in, set the output units to MILS, and created the following drop chart. Before I post that here's my input data (from your first post): Cal: .284 Weight: 180 grains G7 standard selected G7 BC from the website: 0.345 (G1 = .674) Muzzle velocity: 3034 Temp: 72°F Pressure: 29.99 Humidity: 60% Wind 0 from 3 o'clock Site height: 2.7" Zero Range: 100 yards Look angle: 0° 100 0.00 200 -0.20 300 -0.69 400 -1.28 500 -1.95 600 -2.67 700 -3.46 800 -4.32 900 -5.25 1000 -6.25 1100 -7.34 1200 -8.53 1300 -9.82 1400 -11.23 1500 -12.78 Looks pretty close to me. Which ballistic program are you using? [/QUOTE]
