You can shoot .50 caliber darts out of copper tubing but The cone to bore seal will be on the poor side. The standard (paintball) fifty caliber barrels were a hair over .51 and "sloppy" fit was a common complaint.So I just got home and measured my pipes. The 1/2 inch copper pipe internal diameter (ID) measures: 0.53 inches so I think I lucked out and the 0.50 darts shall be ok. On the other hand, my 1/2 inch PVC pipe ID is 0.6.
I hope the one I bought have close tolerances. I bought thme from Target Zone.You can shoot .50 caliber darts out of copper tubing but The cone to bore seal will be on the poor side.

Target Zone Sports started selling the "Close Tolerance" fifty cals (.495 to .498 inside diameter) about three years ago and it made a world of difference! Sometimes you have to take just a hair off the cone for a proper fit but that is a whole lot easier than putting a hair on.
These should help http://www.amazon.com/gp/aw/d/B008NWUVMY/ref=mp_s_a_1_2?qid=1455833718&sr=8-2&pi=SY200_QL40&keywords=50+blowgun+dartsI made a 3 feet copper pipe blowgun. ID is 1/2 inch. Do any commercial/manufactured darts work with it? Thanks!
I would think that the duck tape would add more resistance than using something like packaging tape.These should help http://www.amazon.com/gp/aw/d/B008NWUVMY/ref=mp_s_a_1_2?qid=1455833718&sr=8-2&pi=SY200_QL40&keywords=50+blowgun+dartsI made a 3 feet copper pipe blowgun.

Just wrap duct tape around the cones until you have a good fit.
