yes the blow gun does work extremly well, as long as you mod the internals which is very easy it should work just fine.

That depends on both the bore of the copper, and the wall thickness.
There are so many variables there I can't even begin to try and answer it.

However, in small bore copper (1" or under), unless you're messing around with CO2 or other gas bottles, you aren't likely to encounter a problem.

That`s a nice gun but do you think that the curve in the chamber would take from the guns preformance?
