[QUOTE="entoptics, post: 2696884, member: 104268"] FYI, leading isn’t generally caused by friction or ”skidding” or smearing. It’s vaporization from the flame front behind the bullet. The vaporized lead condenses in the barrel as the temp drops. I believe this is also the case for copper, though much less due to the considerably higher vaporization temp. As mentioned, a bullet that isn‘t tight enough in the bore allows flame to sneak past the base of the bullet, between the bullet and the barrel. This carries the vaporized lead into a cooler area, causing it to condense and deposit. A properly sized bullet will produce a tighter seal, greatly reducing this. Its a similar principle that makes gas checks effective, though instead of sealing, they simply protect the base of the bullet from the flame reducing vaporized lead. [/QUOTE]
