What's really funny, is that the teflon coating of bullets originated in a desire to cut down on the need to clean copper or lead fouling in barrels and to aid in the functioning of firearms. It was also thought to slightly increase velocity. There has been absolutely ZERO evidence that the teflon actually helps penetration over the exact same bullet without the coating. If it did help penetration, then it would also apply to Moly coating bullets, which is actually a more effective lubricant than teflon in firearm/bullet applications.
And no, Ditter, I am not flaming you - just using the info you provided for further argument points.....
