I've tested with darts made from Frost King, converted stock darts, MrCrouse's foam, and others, and nothing makes it through.
I've tried barrels of 12" and 6" on a +bow, Signal Launcher, PistolSplat, and blowing them by mouth.
The PETG doesn't feel sticky or strange - it feels totally normal, but darts just won't let go of the walls.
This doesn't happen with the PETG on Silencer's NF (heh heh).
Any ideas? Should I sand down the inner walls, grease them up, change darts?
