[QUOTE="Michael Eichele, post: 595826, member: 1007"] A feshly cut barrel with tooling marks is rough. A lapped barrel is smooth in the sense that the tool marks have been removed and the surfaces are even but the bore is 'rougher' than a 'polished' bore. Think of a polished bore like perfectly clear glass versus a peice of glass with a very fine frost to it. You want your barrel to be like the frosted glass. It is still smooth but anything but polished. Which of the two do you think has more surface area? Hopefully you answerd the clear peice. The more contact the bullet has with the barrel, the more friction you have, the more fouling you have. The more it is polished, the more the bullet will contact the bore. I understand we are talking microscopic differences here but it is those microscopic differences that make the difference between a barrel that fouls worse than others. I am not saying that the more rough the barrel the less it fouls. There is a VERY fine balance to the right roughness/smoothness for optimum performance. Too rough = bad fouling. Too polished or too smooth also = bad fouling. [/QUOTE]
