After I bought a new.45 GM LRH barrel for my Renegade, I decided to send the badly pitted TC .50 caliber barrel back to TC. I included a letter stating the pitting was caused by impropering cleaningand asking if anything could be done for the barrel and, if so, how much would it cost.

Well, I received the barrel back today with a service order that said "Lapped Bore. Test fired - 50 yards: 90 grs FFg black powder, 370 gr. MAXI BALLS, 1 3/4" group, No Charge."

Ya` can't beat that! The pitting is still visible in the bore, but is notably less than what it was.

Looks like I'll have another chore for my next range session. If you recall my post "Disappointing Day With the Renegade" http://www.huntingnet.com/forum/tm.aspx?m=2736181&mpage=1&key=Renegade&amp ;#2736181 , I shot five different loads at 50 yards with that pitted barrel and hadmiserable results. I'll be re-shooting those loads with the lapped barrel and report my results. Should be interesting.
