[QUOTE="MontanaRifleman, post: 300956, member: 11717"] If we were all paying attention in 4th grade science class we would all know that heat and cold expands and contracts metals. Rifle barrels are no exception. Firing off rounds in a steel barrel will heat it up and change the dynamics of the steel. The more powder and overbore the barrel the more it will get heated after each shot. The heavier the barrel and/or lighter the load, the less each shot will affect the steel - heavier barrels will be able to absorb the heat better to a point, simply because they have more mass. During the barrel manufacturing process, stresses are induced into the barrel. A good custom barrel maker will relieve most of those stresses. Heat from firing will likely have some effect on those stresses in the steel. As already mentioned once or twice, every barrel will be different, but it only makes sense to keep the barrel temps consistant when shooting for groups. I always let mine cool between shots to an ambient temp, or maybe slightly warmer. -MR [/QUOTE]
