[QUOTE="Comancheria, post: 1690693, member: 110141"] Not sure who came up with it--(I [I]think [/I]it was someone famous, like Jack O'Connor, but it wasn't he)--but without regard to bullet weight or caliber, and ignoring the all-important aspect of bullet performance, (and all of that' ignoring a lot!) the old formula that I used to see kicking around oh, in '50s and '60s was as follows: Deer/Pronghorn Size: Minimum = 900 ft lbs/Good = 1,200 ft lbs/Ideal = 1,500 ft lbs Elk/Moose Size: Minimum = 1,500 ft lbs/Good = 2,000 ft lbs/Ideal = 2,500 ft lbs Brown/Grizzly Bear: Minimum = 2,100 ft lbs/Good = 2,800 ft lbs/Ideal = 3,500 ft lbs Whoever came up with that formula obviously used the idea that you picked a minimum for the size and disposition of the critter you were going to shoot, then added 1/3 of that for "Good" and 1/3 again for "Ideal". Pretty arbitrary, but it sure makes a nice, neat rule of thumb! :) Best regards, Russ [/QUOTE]
