[QUOTE="4ked Horn, post: 65326, member: 11"] You are correct (to the best of my knoledge) about the exposed lead at the base being effected. The intense heat AND pressure can be expected to cause an erosion to the soft, low melt temp lead as well as the throat of a steel bore. I am not a big pistol shooter but it is also my understanding that this is one of the reasons for a copper "gas check" to be installed on the base of lead bullets fired from big bore handguns that accelerate slower and are sitting on top of a considerable dose of gunpowder. This heat is sufficient to ignite a phosphorus core on a tracer round even though the bullet is in contact with this superheated gas for less than a pico pico pico second. Now as a side note, I have witnessed a friend shoot a bullet out of a .22-250 and print a nice sub MOA group. He then loaded the same components but either a hotter charge or a different powder (I dont know which) and fire at the same target and not a single round made the trip. Why? Dunno. Maybe the aliens beamed it up mid flight. [/QUOTE]
