[QUOTE="entoptics, post: 2213053, member: 104268"] Use a ballistics calculator ([URL='http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi']Click here for JBM's online one[/URL]), and figure out where your bullet of choice drops below ~2000 fps, or ~1500 ftlbs of energy, at the elevations/temps/pressures you're likely to be hunting in. For example, 160 Accubond, MV = 2650 fps, 6500 ft elevation, 50° F, 50% humidity, 29.9 inHg (corrected), will hit that threshold at ~450 yds. 2070 fps, 1521 ftlbs. Running the same conditions with 160 partition gives about 400 yds. Then figure out what distance you can hit a paper plate, in field conditions, 9 outa 10 times. Whichever distance is the shorter of the two, should be your maximum hunting range. [/QUOTE]
