A friend purchased a new ML and gave me his Triumph. It is a basic blued model. Problem is, after shooting it last season, he reloaded and left it in his cool basement with the charge still in it over the summer. When I took it, I removed the breech plug to let the pellets drop out. One did and the other pellet and the sabot were "stuck" in place. It actually took tapping with a hammer on the ramrod to get them to let go and fall out. After this, I looked down the barrel from the breach end and can see a ring of what is probably rust a couple inches in from the breach plug area. Its nice and clean/shiny where the pellets would have sat then there is that ring. Ive tried birchwood casey products, along with brass brush and also 0000 steel wool and it doesnt seem to touch it. I even tried the rust/blue remover from B/C and that doesnt seem to do anything to the ring I can see. When I push a jag/patch thru, it hangs at that spot and I really have to force it to get it to move past. I tried pushing a sabot down thru and can feel it stick there and then with some force it will pass by.

Basically my question is, is this barrel toast now? Will I need a new one to make this gun even useable?

If I need a new barrel, are they only available from TC? I cant find anything online about barrels for the Triumph??

Thanks all
