[QUOTE="bill123, post: 911703, member: 69116"] I didn't start thinking about this much until I bought a custom gun (GA Precision .308 w/ Bartlein barrel). I did a ton of research and then did the typical break in. Shoot 1 clean, shoot 2 clean, etc... I then shot about 1000 rounds through it, cleaning the powder residue out after each shooting session (patches and solvent only). My shooting sessions are typically 40 rounds of 5 shot groups. W/ 168 gr SMK's my average group was 9/16" over the 1000 rounds. Some of my groups were always 1/4"-3/8" some were always 13/16". After 1000 rounds I copper cleaned. I shot maybe 500 more rounds through it w/ no change in accuracy. My groups only got better after experimenting w/ different ammo. I now have 2,500 rounds through the gun and won't copper clean until the accuracy degrades. I'm not sure that there will ever be one right answer to this question. I suspect that there are too many variables. Quality of the barrel, caliber, type of ammo, how hot you let the barrel get between shots. I've read advise from many outstanding shooters who get consistently outstanding results with completely opposite cleaning strategies. The one question I have is, does powder residue left in a barrel degrade the barrel? Some say yes, some say no. For those who say yes, how are you removing it? According to M-Pro7's Copper Cleaner instructions, bullets leave layers of powder and copper fouling on top of each other. If that's true, then I suspect that even if you clean out the powder until your patches are perfectly white, there is more powder residue under successive layers of copper. [/QUOTE]
