[QUOTE="Cruizin, post: 261607, member: 7095"] I've noticed the same thing and a heavier barrel will help some because the heat dissapation will take longer to heat the entire barrel up, but on the flip side it will take longer to cool as well. I think that once that chamber heats up your round gets hotter due to conduction. The other thing that's happening is the powder is still burning as it goes down the barrel. If the barrel is hot the burn is probably more efficient. I think this is probably most of what is causing the increase in velocity. [/QUOTE]
