[QUOTE="jebel, post: 1713601, member: 106189"] This exactly. You could shoot in deep space and the muzzle velocity would be the same, powder temp accepted. Those are internal ballistics. You’re thinking about external ballistics, the stuff that happens after the bullet departs the muzzle. Your ballistics app and kestral will certainly come into play with differing external conditions, but they don’t have any bearing on internal ballistics (again, powder temp accepted). Remember, it’s internal, external, and terminal ballistics. We have great, accessible data on external, somewhat less on internal, and a mess of poor data and multiple unsubstantiated theories on terminal. [/QUOTE]
