Alright, sorry if I posted this in the wrong place, move it if needed.

I'm trying to figure out what the friction would be for stock streamline darts in 1/2" PETG from OMC...

I'm assuming some people use this combo (obviously) and I was wondering if anyone has the average friction so I can make my barrel length accordingly?

Unfortunately I have no method to measure it myself. :'(

OMC's Thickwall PETG has an amazing fit for streamlines. Also, if you have a rediculously powerful gun I'd suggest longer barrels for 'em. If you have a foot-long barrel on a weak gun, it won't even leave the barrel. What gun are you going to put the Thickwall on anyway?

Edit:: I didn't think you wanted an actual number for friction. To be honest, barrel lengths in my opinion don't particularly NEED to be brought down to a science, but whatever you find necessary go for it.

I would reccomend using something other than streamlines. They have absolutely no accuracy. Use some ctds. They are also come out to be cheaper per dart than those ten packs.

Well, it's for a recon mod I did Here.

Basically I'm optimizing as much as possible (it's a Recon after all.) I already got 13cm for length without taking friction into account, and removing an inch or two makes a big difference I'm sure...

So any ideas? Just take off a 1/2" until it shoots better? (or at all)

Okay, do they fit in the clip? I'm modding the streamlines with 1/4 weights and I closed the holes with glue.

Figure it out for yourself.

I'm sorry, if you don't want to help, you don't have to.

Also I have been trying to, I've searched the boards countless times and I've received information on how to measure it out myself but I lack materials. Also I thought it would be a simple answer since, like I said, I'm sure a lot of people use thickwall PETG from OMC with streamlines.

Again sorry if I'm doing something wrong.

There isn't much in the way of numerical theory for this, unfortunately. The best advice I could give you is to try lots of different barrel lengths and fits.

For what it's worth, I think streamlines are far too loose in OMC PETG to be used in a springer.

Yes, there's an equation, I've been working on a mod lately: Recon Mod

Also, I'm getting stock ranges when I put the dart in from the front.
