[QUOTE="WiscGunner, post: 1765150, member: 97288"] I am of the school of thought that carbon buildup is back, copper is good. I do not clean my barrels bare, ever. After every match (100-200) I run 1 patch wet with Hoppes #9 and a few dry patches just to remove dust and keep the carbon down. I use a bore guide and nylon brush with a cotton patch wrapped around it. I never let the cleaning rod run on the crown. I think a lot of people wear out their barrels with too much scrubbing. Abrasives are bad. Running cleaning rods across the crown will cause uneven wear of the crown. A bit of abrasive to smooth fire-cracking once in a blue moon is about all that is necessary. Carbon rings in the throat are extremely detrimental to accuracy and pressure. You are basically squeezing the bullet smaller to pass through the carbon ring making the bullet sloppier in the bore. Gas blow by is also increased. Carbon buildup in muzzle breaks is also extremely detrimental to accuracy. Both are easy fixes with patience. I run a wet patch of carbon remover past the carbon ring and leave wet over night. If very stubborn, I leave the wet patch in the bore on the ring ahead of the chamber for a while. Trying to speed up the process with mechanical means is not a method without a lot of risk. just my 2 cents. [/QUOTE]
