I cant believe i did this.
I poured Hot water down my barrel this evening.
Using water, is THAT what you can't believe?
i boiled water and flushed the barrel really well and ran alot of dry patches to.
IMO if you poured boiling water down the bore methinks the metal was so hot there's no need to worry about any residual moisture, evaporation would be complete... don't ya' think?
Anyway, good luck with the plastic fouling if that's what went wrong. Figuring these D-ed things is like voodoo sometimes!
