Auto Cartridge Gun

[taz22]

@shrimphead. i don't get it:S how do you give your ammo pressure??
the mag i made will be just made out of square box section and welded a platen on the bottom. the ammo will move up by a spring. how the ammo will stop when it isn't on the weapon i haven't decide it jet. i guess my gun will work because its the same design of a real gun (check http://www.homemadegunsmith.com) this guy make his own guns and make plans for it. the ammo will not be so expensive because i guess you can buy car tire valves very cheap if you buy a lot of them (i guess about 100 so you could fire it.) the mag will have a capacity of 15-20 rounds so you won't shoot many
