Ventura Munitions is currently loading high velocity .32-20 ammunition that is only suitable in modern firearms. I would very much hesitate using it in any revolver.
You're not likely to encounter any of the old Winchester or Peters high velocity ammunition in shootable quantities, but you'll often come across a few rounds here or there.
These rounds will have a headstamp that is different from standard rounds and will include HV (for high velocity) or HS (high speed) or something similar in addition to the cartridge marking.
Never, EVER fire these cartridges in your Colt. They were designed only for the Winchester Model 1892 rifle.
