[QUOTE="crkckr, post: 2696902, member: 78056"] Lead vapor causes the majority of leading but mainly with hotter loads. Another culprit is a rough bore. A rough can literally strip lead off a bullet, which can be a readon your barrel won't shoot lead bullets very well (worst case). That is also the major cause of copper fouling and why the NECO type kits work so well. It is also why custom barrels usually don't foul as badly as factory - the custom barrels are hand lapped making them much smoother and unlikely to collect fouling as rapidly as a rough factory barrel. That does not, however, always have a huge thing to do with accuracy! I have a Savage 30-06 that has a fairly rough barrel but still shoots into an inch. Plus I had a friend with a WWII era K98 that shot fairly decently considering it was only iron sights. Well enough to get his deer every year. I offered to clean it at my home range once and I put a cloth patch on a nylon brush and could feel how rough the barrel felt as I pushed the brush and patch thru. The patch literally came out shredded to pieces! I eventually got the majoriy of the copper fouling out (with chemicals) without doing anything to it's accuracy but it's the only time I have ever shredded a patch to ruin with one pass! It still kills deer dead in one shot! Cheers, crkckr [/QUOTE]
