[QUOTE="Mikecr, post: 2538848, member: 1521"] It's not high density, but high altitude density (per standard conditions for altitude). Or another way to see it: (High) Density-Altitude. Again, all of the confusion with it validates my assertion that DA holds little to no value in ballistics. That's one matter The other bigger matter is that DA is based on standard conditions per altitude, and it would be extremely rare for conditions (wherever you stand) to actually be at standard conditions. This means your conditions must be measured to know your DA (as calculated). But if you're measuring, it's logical to just enter what you measure in ballistic software (without extraneous calcs). After all, if you don't understand this stuff, you will screw it up. [/QUOTE]
