[QUOTE="H-BAR, post: 53297, member: 1281"] First off the idea behind moly is that it is a lubricant and thus the less fouling in the barrel. Anyone that has spent time reading about machining theory has learned about deformation and deposits left behind when machining something. These are the very same principles that happen when the bullet is swedged down the barrel. Just the idea of more fouling being left behind by a non coated bullet is a hint that the integrity of the jacket has been compromised to a higher degree than a coated bullet. There is a reason that you get less velocity from a coated bullet versus a noncoated bullet and using the same powder charge. This reason is in part because the bullet does not compress as much longitudinally which causes the barrel to not seal the gas behind the bullet as well. A noncoated bullet will seal the barrel better because when it gets hit in the butt by 60,000 plus pounds and having a higher level of resistance will compress and fill the barrel to a higher degree.
