[QUOTE="liltank, post: 466411, member: 13275"] There's a happy number that different calibers enjoy in barrel length. Generally the bigger the cartridge, the longer barrel can add to performance. However there is a level of diminishing returns. If you stuff a 30" tube on 17Rem Fireball, you will more than likely see a lower velocity than say a 24" tube. There just isn't enough volume of powder to continue a constant burn efficiently enough to gain any added velocity. The bigger casings such as the 338 Lapua, Allen Magnums, and RUM's, all are designed to hold a large volume of slow burning powder that will produce higher velocities to a point. Dan Lilja did a nice article on his sight about this very subject. The 338 Edge and Lapua are ballistic twins. Both however require a minimum of a 26" barrel to really take advantage of the powder volume each uses. 28" seems to be the optimal length, but then again 30" wouldn't hurt it either. A matter of rigidity isn't really the concern IMO, on the length. It is more of a weight issue, along with being to long to lug around in the brush should that situation present itself. But when you look at the 338 Norma Magnum, it is designed to shoot from a shorter barrel. It will perform equally well if not better with a 23.5" (suggested by author of the article on this sight) than the longer case 338 magnums. He suggests that 23.5 to 26" is the optimal lengths for that caliber. Any longer than 26" and you are not gaining anything. The longer case magnums need the extra length to use the powder up.
