Actually Charlie, It's powdered iron. Magnesium is non-magnetic. Dry powder magnaflux is generally a good inspection, but it would be difficult to do a thorough job, because the barrels, being long, and very narrow, can only be exposed to a magnetic field in basically one direction.
Your suggestion of going to an automotive shop isn't a bad one though, as most also to visable dye Liquid Penetrant testing, or flourescent penetrant (Similar, but uses a black light)
I thought the barrels in question were steel? Didn't I read V grade? They should be repairable.
