My understanding is that the JBM range card function uses density altitude. My understanding is also that the temperature inputs are for transonic calculations. Density altitude is pressure altitude corrected for temperature, and, to a minute extent, humidity. It is a measure of air density. 4000 DA is 4000 DA whether the temperature is 0F or 120F.

So, for these six loads, we fired five-round groups from a benchrest at 50, 100, 150, and 200 yards. We zeroed our rifle at 50 yards, so that's our starting point. At 100 yards, the subsonic loads dropped more than 7 inches. The Stinger has about 50% more velocity and it only dropped two inches. Moving out to 150, the gulf between the fastest ...Ballistic's world renowned JBM ballistics engine delivers the gold standard in calculations that other applications compare themselves to.
