Velocity? Not really. I'm already dredging from memory, from over fifty years back.
Phil Sharpe wrote of a Frankford Arsenal experimental "gun" that managed to get a ten-caliber, ten-grain projectile well above 5,000 ft/sec, but I'd have to go hunt it up. Sometime in the 1930s...
I think I read somewhere that the maximum velocity of the pressure wave of burning gunpowder is around 10,000 ft/sec, but don't quote me on that.
