lets say 50 bucks is my aim, golf ball size ammo roughly. My meanest combustion cannon had a 1.5' breech loading barrel and it had twice the range of my other guns. just wasnt half as loud or menacing looking lol.

ok guys, i realize this gets asked probably a million times a day. But I have tried combustion cannons, and had a blast.
