Emerging smokepowder weapons in my fantasy

Of course the barrel heats up, but it takes three times as much to heat up an orichalum barrel than a bronze one. Note that the Ignite Fire is effectively cast by the magical item in question and doesn't heat up the item itself any more than a wizard casting Ignite Fire has his fingers burnt. But obviously, the combustion of the smokepowder heats the barrel as normal.

Not that firing often enough in a minute for that to matter is likely to come up with a holdout gun like this. The PC probably can't even manage more than 8-10 shots in a minute, even with succesful Fast-Draw (Ammo) rolls and no Aiming. I can't really imagine a situation where he'd fire often enough to overheat an orichalum barrel with magical protections.

In any case, the only danger would be ammunition cook-off. The PC is immune to fire and the orichalum weapon is Fireproof, Shatterproof and Soilproof.

Fast-Fire smokepowder is a good idea, of course. Maybe not the basic load, but definately specialised ammo.
