I have been seeing some stuff about barrel conditioning, nothing detailed, just some mention of it. I have an 8 year old Knight Disc extreme .50 cal stainless barrel. I did not do anything special with the barrel when i bought the gun, just worked up a load and hunted. The gun is accurate and clean. Question? should I do something now to condition the barrel or is it too late or not important at this time? I am shooting Blackhorn and 250 and 300 gr. Thors. Thanks for the help.
