[QUOTE="CONatureBoy, post: 2254795, member: 118769"] QuickLOAD predicts a muzzle velocity of 3,069 fps from a 300 RUM shooting a 200-grain .308 Nosler Accubond (product #54618) in front of 99.9 grains of Reloder 33, with a cartridge length of 3.598" (the SAAMI maximum), at a peak chamber pressure of 64,917 psi.
