[QUOTE="MudRunner2005, post: 1092974, member: 12995"] Friction and heat from the velocity of the bullet traveling down the bore, and more heat from the powder burning... Friction causes heat and erodes metal... For example, grinder wheel vs. steel tube. Which is the same principle as to why those David Tubbs fire-lapping bullets work so well. However, I think what JE was referring to, was parts of the copper jacket that are torn off from machining marks, filling in said machining marks in the rifling, creating a smoother surface for the next bullets to ride along, until it starts building up too much, which will throw your shots down range. Then it's time to clean it good, and start over re-fouling your bore with a couple fouling shots at the range, and you're good to go again. If copper jacketed bullets are not capable of smoothing out machining marks, then why do we even have throat erosion, and rifling erosion in steel barrels? Why would anybody ever need to re-barrel a rifle, other than to change caliber? Nobody would ever have to worry about barrel life. Think about it that way. :cool: [/QUOTE]
