[QUOTE="Mikecr, post: 703631, member: 1521"] No, I'm sure Dan knew just what he was doing. His test was an exploration, with his conclusion being: --------------------------------------------------------------------------------------------------------------------- For lighter weight, walk-around-type hunting rifles chambered for big cartridges like the 338/378 Weatherby magnum, extra- long barrels are not going to gain any significant velocity increases. As I found out too, long skinny barrels are whippy, especially with the high recoil cartridges and loads. My recommendation is to use no longer than a 30" barrel with a minimum barrel contour of a #4. A better choice would be a fluted #5 or #6 contour. Barrels over 30" are going to have to be heavier to counter the "fly rod-phenonomen" and will probably be too heavy for most walk-around-type rifles. Or rather, too heavy for the gun bearers. --------------------------------------------------------------------------------------------------------------------- 30" & 7-8 pound barrel. Sounds rational to me. But then, this test did not include accuracy or precision in barrel choice. He implied those factors, which probably represents his experience with the cartridge. I'm also referring to a balance, that includes accuracy and field functioning. But we don't know for sure yet what fastfire57's 338AI is going to be [/QUOTE]
