hi guys, i am from brazil an made my douchenator

but i still have some questions about the ammo

i used some table tennis balls and they get something like 3 meters of height

but when i use potatos and stuff like that it only flies 2 meters...

am i using to few pressure?

and which ammo do you guys thing that it's the best one?

I'm not quite sure what you're asking for, but I'll try to help. Try putting in more pressure if you want more range out of it. That, or make a bigger pressure chamber. Also, ammo-wise any of those should work great, Dux recorded range of around 100 meters.

You need to have a can in the barrel behind the item you are shooting. Or you could put the item in a can. Either way you need some sort of can/cup in the barrel to make the seal and catch the air. Only that way will anything shoot far. Pringles cans and tennis ball cans work best, but plastic or paper cups also work.

oh, sorry for my bad english

my pressure chamber is actually like 2x the size of the videos

but maybe i am too afraid, i am doing only 30 pumps with those

maybe 30 is to few huh?

thanks for the respone anyways guys

30 pumps should be enough, but read the meter to make sure. You want 60-100 PSI for good [400-600ft] of range. Make sure to put the can in behind whatever it is you are shooting as well. Without a can/cup in the barrel, objects will not catch all the air and will not fly far.
