[QUOTE="montana west, post: 1949473, member: 113504"] how to figure energy in ft lbs. velocity x = over 450240 . in a caculator the velocity X = squares the velocity the devide by 450240. 450240 is 64.32 x 7000 which converts grains to LBs. example the 416 Taylor which is the same as the 416 Ruger in vel. a 400 grain bullet @ 2410 2410 x2410 = 5808100 devided by 450240=12.90 12.90x400 wt of bullet = 5160 ft lbs of energy.. this is why the 416 is now the go to gun in Africa it has more down rang energy than the 458 winchester. with less recoil and now the 416 Ruger is or will soon be the king of the 416 because it performs = to the 416 remington and the factory loaded 416 Rigby.. All on a 2.5 inch case I like the Taylor of which I like better because, I do like a belt on a round this large. P O Ackley taught me this. In his chicken house converted to a barrel making and gun building enterprise. 1976 [/QUOTE]
