I was simply trying to make a fellow shooter feel good about his choice of rifle and caliber, and to some of us 300 to 400 yards is Long Range . However , please forgive a really dumb question, but "What do we actually classify as a LONG RANGE HUNTING Cartridge??" Is it a round that can take Mule Deer or Antelope cleanly at 800 plus yards. Is it a round that can take Elk at 800 yards??? If a bullet with a High BC is still super sonic at 800 ,900 or 1000 yards does it qualify as being a LONG RANGE HUNTING Cartridge?? If so , what about energy at those ranges. Do we have suggested Guidelines for energy being delivered at those very long ranges. So as previously pointed out, this is a LONG RANGE HUNTING forum, not shooting 101 , so what's the formula??? OR are some rounds really just LONG RANGE TARGET Rounds, capable of hitting a 6 inch plate at 1000 yards but may actually lack the energy to properly ,cleanly and ethically take game at those extreme ranges. I can say that my . 270 Weatherby Mag, with a 150 Grn Accubond LR , fired at 3000 fps, from a 26 inch barrel , even at 4000 feet altitude , does not retain sufficient energy for me to shoot at a mule deer at 1000 yards, even though the projectile is still traveling at supersonic velocity . In My Opinion , the energy just isn't there. So, Just wondering what the Velocity / Energy / Range guidelines are to classify a cartridge a true Long Range Hunting Cartridge?
