[QUOTE="J E Custom, post: 396057, member: 2736"] Typically the magnums benefit from extra barrel length because of lots of slower burning powders that they use. The cases with less than 50 grains of case capacity can use shorter barrels. So the magnums will lose about 30 to 40 ft/sec for each inch of barrel loss. so you should lose about 50 to 60 ft/sec going from a 26" to a 24" barrel on the 300 Win. These velocities will vary some depending on type of powder and the barrel and chamber combination. J E CUSTOM [/QUOTE]
