I am just learning about LRH, but have been a hunter and a avid shooter for many years. My hunting has been in western PA where 'long range' was less than 100 yards, and most shots within 100 yards. I am starting to get interested in LRH and beginning to do some research and planning. A 308 can push a 180 grain bullet at 2700 fps. If we get more specific, and look at a Hornady Interbond (which has a BC of .48), then at 500 yards, then the bullet is moving at 1849 fps and has 1366 ft.-lbs. of energy. At 800 yards, the bullet is moving at 1438 fps and has 826 ft.-lbs. of energy. For comparison, if the muzzle velocity were 3000 fps (launched from a 300 WinMag or 300 WSM), then the distance would be extended by approximately 150 yards (A 300 Magnum at 650(950) yards would have a similar velocity/energy as a 308 at 500(800) yards). Obviously, how far depends on what game is to be taken. But shot placement is more important than 'explosive', 'devastative' expansion. When I hunt, I work hard to take shots that will penetrate both lungs & tag the heart. So, how much velocity/energy does a 180 gr. 30 cal. bullet need to have WITH proper shot placement for deer/antelope, and for elk?
