With out rifling will the pellet just tumble in midair?

I just go to Target and they give me them for free!
I have a box of about 30 of them.

"They found no ammunition for the most dangerous weapon, the assault rifle."

What is he going to do with a gun with no ammo?

Do you mean one of these?

This is just insane! A kid gets arrested for owning a bunch of airsoft guns. I know a guy who owns about 100 real sporting rifles and nothing has happened to him. I agree with windshrike on donating a couple hundred dollars to the NRA.

Where can I find a quick-exhaust valve that can hold 300 psi?
I can only find up to 150psi.

Would it be safe to use a metal quick exhaust valve and blowgun at 300 psi?

I told the a guy at Homedepo what I was doing. He laughed and said he used
eggs for ammo.

I would be careful with putting a scope on there because if it gets hit by a paint ball... You might want to get a red dot sight or really strong scope covers.

For rna_duelers design just put your hand over the barrel when you pull the pump and take your hand off when you push it.
Also be sure that you pull the pump as far as it will go or the pressure will blow that whole thing off.

I think this would be easier to operate and quicker to open and close thus letting less bbs out.

Does the shock pump connect to a tire valve?
Also would I need to make a piston or is their a metal sprinkler valve that I could use and would a blowgun be be strong enough to use as a pilot valve?

Would that shock pump connect to a tire valve and be able to fire the .22 air rifle round at a high velocity?

Would this work for an air source?

I want to make a high powered 223 cal. gun and I have some questions.
What type of pipe should I use?
What type of valve should I use?

I would like the barrel to be thick enough so that I can have it rifled over at Gander Mt.

If I could have some help that would be great.
