Called TC/SW this morning and the result is they are sending me a shipping label to send the barrel back for a replacement. I'm mad with the problem but at least I get a new barrel. Second one had better be on the money! FYI, the felt recoil between the Triumph and Omega was a bit more than I thought it might be with the Omega giving more with identical loads.
When I suggested I would try a different weight bullet they said you'd better just send it back for replacement. Tells me maybe they have had recent experience in this matter??? Dissapoints me as every other ML rifle has been problem free and we're talking 35 years give or take a year! The Omega bullet impacts look like small spaceships... probably not a good thing
