Not bad. Any damage pics? What kind of performance are you getting with it?

looks good, the only thing i would change on it would be the barrel length, its a little to short(although it is a shotgun), but other than that very nice job. :D

are there any reasons for the smaller chamber or bigger barrel or is it just for aesthics. I would love to make this thing better in anyway i am completely open to critism or ideas

ill have some damage pics in the next day or two maybe even a video of actual fire

any suggestions on shells? i made a new shell its a flash car cut in haft, rolled up to fit in the barrel a little wider in the back (so it doesnt fly out the barrel), i put a cottonball in the back for wadding, filled it with 50 airsoft bbs and masking tape to cover the other end.
Is a cotton ball a descent wadding?

Edited by jrrdw, use the edit button if no one posted under you. No more double posting.



ok since no one has commented and i dont wanna double post ill just edit this one
i know i promised some damage pics and a video but the seal on my sprinkler valve where the solenoid was broke so im currently putting new epoxy on it . but i did manage to shoot it off. i actually had my bro fire it so i could see the patern nothing it has penatrated cardboard from about 20ft so idk wat that means but i think the spread is wayy to wide. any suggestions? i think like some of you said a longer barrel would help

You can make it a bit neater like this and cut down on the dead space between the projectile and the valve:
