I've had my Renegade for a pretty good number of years and you are now stepping into my world of sidelocks. I also know several people with Renegades in both .50 and .45 and neither they nor I have ever had a barrel issue. And we all have thousands of rounds through them. I can still keep PRB's under 2 inches at 100 yards with mine. Under an inch with XTP's, the only sabot the thing will shoot worth a damn, is still easily attainable. I doubt seriously you had a barrel issue but an operator issue in not knowing how to clean properly or more than likely not knowing how to shoot the thing properly. The Renegade is one of TC's best shooting rifles of all their productions. I am starting to suspect all your posts to be some sort of brand bashing attempts.
