I once owned a TC Renegage in .54 cal percussion, and eventually the barrel stopped shooting the tight groups to whichI was accustomed. Not sure why.
caionneach... who knows? I may have become the proud owner of that 54 Renegade you discarded. Many shooters are just like you -- in that they don't have any clues as to why their gun suddenly stopped being accurate. So instead of searching for the answers, they opt to buy another ML. Well... that's where I say
"Thank You Very Much"
I constantly buy & sell Renegades & Hawkens from internet sources. Shooters sell them... sometimes give them away thinking the barrel is shot. I love all those soap & water bore users who go out & buy new rifles that end up being inferior to the one they just sold for $95 -- thinkin' it only had a good lock, trigger, couple scratches in the wood.... so it can't be worth dickens.
Keep em' comin' boys.... many times for only $4, I can turn that bore completely around into a wonderful shooter again.
