[QUOTE="John Spadaro, post: 1521355, member: 107723"] I have looked up the specs for each cartridge on the Hornady website using the Precision Hunter ELD-X data. Here is the comparison between Cartridges at 400 yards. Velocity Energy Drop Bullet Wt. 6.5 CM 2156 1475 -22.4 143 6.5 PRC 2381 1800 -18.2 143 270 W 2306 1714 -18.8 145 270 WSM 2414 1876 -17.1 145 7MM-08 2173 1573 -21.6 150 280AI 2291 1888 -19.8 162 308 W 1984 1556 -25.5 178 30-06 2114 1766 -22.4 178 Here is the recoil for each cartridge in a 7.5 lb Rifle. This is an approximation as the formula requires the powder load which isn't specified for the factory Hornady cartridges. [IMG]http://www.shooterscalculator.com/bar-graph.php?h=300&data=14.53,6.5 CM;20.62,6.5 PRC;21.32,270 W;26.08,270 WSM;22.21,280 AI;17.19,7MM-08;19.3,308 W;26.73,30-06 ;&t=Recoil Energy of Various Rifles (ft.lbf)[/IMG] Now the question is how much energy is required to kill an Elk at 400 yards. I have heard quoted Velocity greater than 1800 fps and energy greater than 1500 ft/lbs. If that is true then any of the cartridges I have looked at will be adequate. The 6.5 CM and the 7MM-08 have the least recoil but I think I can tolerate the 308, 6.5 PRC and 270W. Of all these the 270 would be the easiest to purchase. [/QUOTE]
