Ok, i ordered my PETG from Mc Masters...but my FBR seems to be a bit too thick for it. Also, unlike brass, I cannot just push the dart in, it must be twisted in, which makes my ROF much slower. I need to know what FBR i should buy if there is a difference in different brands. Or if some brands of FBR are smoother than others so I can push the dart in instead of twisting. Stretching darts would be my last resort since it is a hassle and takes a lot of time. If anyone knows a good quick way to PERMANENTLY stretch (since when I stretch my FBr it just pops back into its old position after 2 hours). Has anyone else bought PETG from mcmasters so I kkow whether the problem is my FBR or the PETG. Cxwq you said your darts were almost loose inside the PETG. Have you tried any of the MC masters PETG. I guess if I have to I will buy some from you...but I just spend lots of money on like 24 feet of this stuff so please help me!

The problem is that FBR has extremely variable measurements, even with the same manufacturer. I have a batch of FBR that was cut from the same spool and it varies by as much as 1/64" in diameter. That doesn't sound like much but it's enough to change a loose fit to a tight fit.

What you really need to do is buy a whole bunch (hundreds of feet, it's cheap right?) of FBR, measure the average diameter as close as you can - at least two decimal places. Then you can find the materials that give you decent fit on your FBR.

so then a good solutioon would be for me to buy some of your FBR if you are willing to sell some...?

Um. No.

You may have good luck with loghelp.com though. That's where I got mine.

See, I bought 900' so I'd never ever have to buy any again and I'd always be assured of having a safe supply. And then half the people in SoCal started using my darts/foam. Now I'm down to about 600' in a year or so. Scary shit.
