Ballistics and the Drag Formula
I’ve recently taken an interest in firearms and one of the things I’ve been trying to understand and model the behavior of a bullet in flight. Unfortunately, a lot of the tutorials out there are a mess with confused notation, sloppy units, and missing factors of π. This makes it difficult to write a simulation that is consistent with other models, let alone accurate. Here, I touch on the basic formula required for a model good up to intermediate distances (e.g. 500 yards).
