Two years I bought what was supposed to be a new T/C Omega X7 (short barrel). The rifle had scratches so Gander Mountain gave me a discount. Got it home and when I buttered the barrel I noticed it was fouled. Cleaned it up, sighted it in with no problem. While cleaning it recently and reassembling it, the trigger snapped in half. Sent it to T/C who fixed it for free and did an inspection. The factory found that the barrel was pitted. Since I clean and re-butter/oil all of my guns periodically, I know that the Omega was pitted from the powder residue that was in it when I bought it.
My question is should I buy another barrel? The gun patterns nicely with open sights but will things get worse?
