Rifles and Munitions transonic ranges
I'm looking to try to find a collection of ranges that different rifle and munition setups can keep a bullet above a transonic speed. I'll define transonic as:
mach 1.2 = 1 339.72441 feet per second (from google)
To try to get a little more information I'd like to get submitters to give information(if possible) related to reloading specs, bullet specs, muzzle speed, enviromental data, etc.
