[QUOTE="speedengineer, post: 1982644, member: 112986"] Bumping this thread, looks like Hornady's ballistic calculators still disagree with other calculators when calculating solutions for uphill/downhill shots. Ran some more detailed numbers today for a 7mmRM in both JBM and 4DOF. The difference between the solutions becomes VERY significant at larger angles and ranges. Not that a 40deg 1000yd shot is common....but hornady calculates 70 inches LESS than JBM does. A shot of 600yd at 30deg would still put you low by a foot!
