I have bought these two non-nerf pistols from walmart that shoot sits darts sort of a revolving system like the ATs. It's a plunger gun with about the same plunger size of NF. I was wondering which type of barrel would be the best to shoot micro stefans. PETG, brass, PVC or crayola?. I read up on CX's article but it didnt give me much on micro stefan shooting pistols.

You're asking the wrong question. What you should be asking is what is the best barrel for your darts.

Make a batch of stefans then take them out with you to test fit. You can ONLY use what fits YOUR OWN darts best.

Good point. But I was thinking about the whole case of spring guns and air volume and friction, the technical mumbo jumbo. I ALWAYS test fit my darts first but I was hoping for an answer based on the science (if you want to call it that), behind the barrel choice.

For spring guns, you want a tight fit, but not too tight that the darts don't come out. For pump guns, you want a loose fit, but no so loose that the darts fall out when you run.

So in other words, for my spring pistol I'm looking for any giving barrel that I will have to use a ramrod to get the bullets in but not so tight that they will get stuck?

I'd go with cpvc on a springer and probably some petg or brass for a pump gun.

There's a reason why cx spent some time writing that Darts and Barrels article. I suggest you read it. It works out mathematically (I've recalculated it myself a few times) and logically as well. If you really want to get into the scientific "mumbo jumbo" then I suggest you set up an apparatus with brass and FBR and timed light sensors and calculate the coefficient of friction from brass to FBR, but I doubt you have that time.

Yeah your right I don't really have the time (or understanding) to set up a test like that. I read it and understood how the ratio's and all the forces and volumes and such but I didn't really get how that was supposed to help me pick my barrel. Like looking at all the barrels I could be using, which parameters should be met for the ideal barrel? i.e. dart leaves barrel once plunger is done or what not. Hopefully with the parameters I need in my head I should be able to get the rest done by myself.
