[QUOTE="SBruce, post: 532342, member: 21068"] +1. Barrel heat and lack of cleaning contribute more to short barrel life than velocity of the bullet IMO. a decent barrel should give you at least a few thousand rounds at 3600'/sec. don't let it get so hot that you cant hold onto it, and try to clean good at least every 50 rounds. I did that with my old 220 Swift and got somewhere between 4500 and 5000 rounds through it before it needed another barrel. Most of it's bullets were going around 3600'/sec. You may have to chase the throat as it erodes, but that will happen with any velocity. I've heard and read that 243's have a short throat life due to the case design.? I don't have personal experience on that matter however. [/QUOTE]
