All three of ours say Big Boar rather than Renegade right on the barrel, though in all respects they're single-trigger Renegade Hunters and 1:48. My pard's has the QLR, while neither of mine do.
If you're after a flinter and can find such a thing, I highly recommend it. I'm aware that once upon a time GM made drop-in 58 cal flint barrels for the Renegade/Hawken if you can locate one used. As I recall they are 32" and 1:72, but I'm ready to be corrected.
The same hunting pard with the Big Bore has the GM 58 barrel in cap, and it's a dandy too. From what we've been able to shoot and measure, there doesn't seem to be any accuracy difference between the 1:48 and 1:72, but the theorists in our midst will start spouting formulas now that I made that claim. I'll stand by what I see on target paper over what can be read on computer screens, though.
