I have a 50 cal. TC White Mountain Carbine I got from my dad. Back in his younger partying days he hadput it up in a closet after shooting and forgot to clean it. I've always hunted since I was about 10 years old, but started getting into ML'ing the last 5 years or so. I knew he had a couple ML's so I asked him about them. (He hasn't shot in about 10 years). He has several of them. The Carbine was the only one put up dirty. Anyways I cleaned it up and there was considerable rust in the barrel. However it is still very accurate out to 75 yards. Which isn't bad for a Carbine anyways. I killed my first ML deer with it shooting a patched roundball and 80 gr. Pyrodex. I have 2 other ML's besides that one now, but still like shooting it. I'd say if yours may be ok for lighter loads. I was surorised that old TC was still accurate.
