It is a good idea that gun barrels remain cool, but we just don't know how to do it easily.
A friend told me that in World War II there was a gun that had a cylinder around the barrel that you filled with water to keep it cool. I'm not sure what gun it was ...
Do a Google search on the follwing terms:machine gun water barrelYou will find plenty of info on keeping gun barrels cool.
Water-cooled machine guns date back before WW1. The problem with gun barrels getting hot is not because of the bullets, but by the very hot gases caused by the exploding propellant in the cartridge. Unless you use a very highly compressed gas to propel the projectile, such as a BB air gun, you have to use some kind of burning propellant. Gatling-type guns get around this by having multiple rotating barrels.
heat aids in expanding the gas used to move the bullet, a cold bullet would decrease the effect. there is also no way for a bullet to be that cold.
