[QUOTE="davkrat, post: 955869, member: 6452"] Here's some examples of 2000 fps energy values for various weights: 130 gr - 1155 ft/lbs. (Little light but I believe it meets most state's minimum muzzle energy requirement for elk.) 150 gr - 1332 ft/lbs. 168 gr - 1492 ft/lbs. (basically that magic 1500 ft/lbs) 180 gr - 1599 ft/lbs. 200 gr - 1776 ft/lbs. 230 gr - 2043 ft/lbs. Many manufacturers claim that their bullets will expand at lower velocities but what they call expansion is not exactly anything to brag about. At 2000 fps even the sturdiest of bullets will tend to expand reasonably well. I like to have a fudge factor built in. Real life seems to present plenty of opportunities for Mr Murphy to come along and fudge things up. [/QUOTE]
