I made a 3 feet copper pipe blowgun. ID is 1/2 inch. Do any commercial/manufactured darts work with it? Thanks!
Commercial darts for 1/2 inch pipe

Check out this site, you may have seen it already but they have lots of .50 cal products. I'd email them and see if they will put
a caliper to a cone for you and give the measurement just to be sure.
Not a bad question as 1/2 inch pvc pipe inside diameter is actually .60 cal.

1/2 electrical conduit is @ .62 cal. 6 inches of thera band gold is actually 5 inches. A 2X4 piece of lumber is not. The whoppers on TV never look like the ones at Burger King. I just found out this year there is no Santa Clause

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.
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.
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.
