Wondering how long .357 supersonic lasts out of the 5 inch bbl. Do you think we get 50 yards before it drops to sub sonic?
If you know the ballistic coefficient of the bullet, and the muzzle velocity, is that enough to at least calculate a rough estimate of how long it'll stay supersonic? I don't do any long-range shooting, but I've always assumed that's one of the pieces of information that ballistic calculators would give you.
