[QUOTE="Dave King, post: 136849, member: 3"] It really helps to know a bit about the conditions where you'll be hunting, here's a little data on three different locations all at 40 degrees F. For long range there is much to consider and those handy sea level and 59 degrees F. charts stop being useful at about 500 yards. From JBM ballistics: ********************* 200 grain .588 BC at 3,100 fps 40 degrees, Sea level 800 yards = 1,560 ft/lbs 1200 yards = 875 ft/lbs ********************************** 200 grain .588 BC at 3,100 fps 40 degrees 5,000ft Above Sea Level (ASL) 1000 yards = 1,504 ft/lbs 1400 yards = 933 ft/lbs ******************************* 200 grain .588 BC at 3,100 fps 40 degrees, 10,000ft ASL 1200 yards = 1,532 ft/lbs 1600 yards = 1,032 ft/lbs [/QUOTE]
