New to the forum and not afraid to reveal ignorance. I have a Savage Axis heavy barreled 243 that I love to shoot. Mostly targets of one sort or another. I had it down to a .75 moa and was tickled. Ha being said that, I decided to clean the barrel trying to get tighter. It took 14 rounds after that to get bac to a respectable group. How in the world do competition shooters scrub there barrels and go back out and compete? I swore I would never scrub a barrel again but I know it's needed. HOW DO THEY DO IT.
