So long as altitude, barometric stress and humidity continue to be continual, an increase in air temperature will lead to a flatter trajectory on account of a lessen air density (fewer collisions with ‘air particles’ per device duration of flight route).
Great query. We didn’t watch for it settle back again down to ambient. They were shot in the extremes. That will have effectively be tests the consequences of storing ammo at extreme temperatures, which I don’t Assume would've in close proximity to as extraordinary of an influence.

So it's possible a fascinating option imr enduron powders for Those people that really accurate for temperature, but don’t have a device as sophisticated as the mentioned Kestrel Elite meter. Liniarity is often woth one thing I guess.
