[QUOTE="Mikecr, post: 1071485, member: 1521"] My testing led me to these notions (what I think): If you're leaving any petroleum/cleaning products in your bore, you've probably ended up in the 'barrels need to be fouled and left fouled as long as possible' crowd. I believe some here have made sense of this in their minds as needing buildup of carbon, some of copper. But really it's need of burning out enough cleaning residue and then establishing good enough fouling to stabilize performance. Everything should be qualified and there are rough bores that seem to benefit(result-wise) from fouling buildups in the bore. But this is ALWAYS a limited window. A good lapped aftermarket barrel can go longer before copper fouling out to ~80% of peak performance, then considerably less in falling to ~60%. Now, if you've never reached the best from your barrel,(rough/poor bore, bad development/shooting) you're less likely to see what copper is doing to you. You might even get the impression that a lot of copper is 'good'.. The point blank BR folks are shooting at a level where they detect otherwise, and they can't live with ~80% performance due to copper. It appears to me the tactical/assault weapon folks couldn't detect anything without a spotter. Sorry, that's as civil as my perspective has developed there. I was brought up to put guns away cleaner than pulled, so I'm in the 'guns maintained perpetually pristine' crowd. Since I need the capability of pulling a stored/clean gun and hitting well within 1/2moa as far as I'll shoot, on the first cold bore shot, I've put some efforts into doing this. Hadn't seen these efforts over at 'the hide'.. A key step in this endeavor is dry prefouling after cleaning, and use of coated bullets(with same material). I've used WS2 for this well over 20yrs now.It works perfect, and it cleans out. So when I clean a bore, I take it to dry white(more like light gray) metal, and then burnish in dry tungsten. My bullets are burnished with the same powder. This is my fouling. I don't get copper or carbon build up, nor would I allow that. I don't have solvent migrating down into the action/bedding/trigger(there is none), and I don't have to burn it out before crediting my shots. Good fouling isn't copper. While I have offended, I am as offended, and it's my opinion. [/QUOTE]
