One for the guys who are good at maths I guess
Just for fun, I'd like to know if anyone knows the maximum velocity a bullet can travel at without coming apart?
I know there are the gag cartridges like necking down a .50BMG to .17 for a rimfire bullet but that they're just fun, and read Weatherby tried to get a 5,000 fps cartridge going for a record but fell a few hundred fps short.
Anyone know how to work out how fast you can throw copper, the maximum velocity before it comes apart?
