[QUOTE="Trnelson, post: 640917, member: 42308"] Not to muddy the waters with facts or start a flame however some facts listed are not correct and merit polite correction. First is that why the AMU used the 30/338 Win for several years instead of the 308 Norma Magnum when they were concurrently available? The 30/338 winchester was created in 1958 by Fred Huntinton of RCBS fame. It was designed specifically as a 1,000 yard bench rest cartridge and an improvement to the 300 H&H Magnum. According to the Sierra Edition V 5th Printing Manual the 30/338 is superior in terms of velocity to the 308 Norma mag in 150g, 175g, 190g, 200g, and 220g. It is also more efficient than the 308 Norma Mag as it requires less powder for the most part to achieve the same velocity for a given bullet weight. The 308 Norma does have a neck that is .018" longer than the 30/338 and .053" longer than the 300 win mag. Typically rifles chambered 308 Norma mag have a free bore area of 5/32" to 7/32" which doesn't do anything to improve accuracy as it makes it nearly impossible to load without jumping the bullet more than .010". The 308 Norma mag is a fine cartridge in its own right, and is effective, however it simply is not superior to the 300 Winchester mag or even the 30/338 Winchester. YMMV [/QUOTE]
