[QUOTE="mrultramag, post: 642839, member: 4467"] FYI- thats not the reason we let the barrel cool after 3 shots. Barrels tend to last much longer, especially in the throat area; when you do not continue to shoot once it gets piping hot.... nothing to do with accuracy... although on factory rifles the accuracy usually goes south as the barrel heats up. the smaller the contour of the barrel and the more powder the cartridge uses make the barrel heat up faster... thus letting it cool every 3 shots... maybe a 223 with a bull barrel might be able to shoot 10 times before the barrel is piping hot... YMMV [/QUOTE]
