Shame on you for using my homepage as a reference .The can needs to be coke though.
You know that if it shoots through both sides, thats only 340 fps, thats not that painful.

You ought to be proud

Now pcguy is gonna track me down and change my homepage to spudfiles. But back on topic, how far do you and your friends usualy play from each other?

Well, they weren't coke cans, and I did have them up against something so they couldn't move. I also don't have any .2 gram BBs, only crappy .12s.

Then you really need to read jacks link to see how extremely inaccurate you are on those readings.

I did, and it was slightly depressing.

Interesting read this thread,Im looking at making another Semi Auto myself but in 6mm and using a better feeding set up than in my Pitbull 9 semi Auto .It cant take more than 120 psi and 9mm BB ammo is expensive so I'll go 6mm this time but still unsure what bb feeder to use?,blow forward looks to be pretty finicky/complicated?.

The 2 T- Fitting type feeders Jack provided links to= I would suspect they would at least double/tripple feed even with a tight tolerance mag tube!?. Again I'll be using a 1/4" QEV + Poppet Valve as per 9mm semi as it works well

Not if made well. That's the issue really.

The gun is now about 90% done. Literally all I need to do is attach the barrel and magazine. It looks kinda funky right now but everything is hooked up and I can dry fire just fine. I have everything hose clamped, including the propane tank stock and the trigger handle set up. As soon as I slap the barrel and mag on, it will be finished. I don't think I'll paint it because I like how it looks the way it is right now. Pictures soon, hopefully.

Sounds like a personal problem.

EDIT: That was "rude" so anyway, since it's strictly "Semi",
And shoots airsoft BB's (which are little over 1/4").........

My thought, why not use a two stage trigger:
The trigger connected to the magazine OR magazine sleeve,
You pull it back, dropping in a shot and blocking the hole in barrel,
On fully pulled back, it closes a switch and vents the pilot electrically?

Still simple and nice trigger pull for airsoft size. 8)
