Well? What would it be?
I was trying to make rules for the Brickarms automatic shotgun; the one with the fatass drum mag. I made up rules for how it fires successfully, but I'm totally unsure about pricing. A regular minifig's bastard shotgun (range 6", damage 1D8+1-1 for every inch of range) costs 4 CP, so what should one of those made automatic cost?
