For setting up a gun to handle shooting inside of 500 yards...which do you choose...lghter bullet, less BC but higher MV or heavier bullet, more BC and less MV. The caliber is a .284 Winchester (1 in 9" twist barrel) and the game I'm after is elk. I know that the most accurate load is ultimately the winner but please read on. I'll be testing the 140gr AB, 154gr SST, 160gr AB, and 162gr SST (and A-Max for target shooting). I've compared the book numbers for velocity and kinetic energy but I'm looking for actual experience. I know that heavy for caliber bullets are the ticket for LR shooting...lower initial velocity but better retained downrange energy. But at shorter range (0-500yd) is the heavier bullet and higher BC (160gr to 175gr bullet) significantly more beneficial or am I better off w/ more velocity and higher impact speed from a lighter 140 to 150gr class bullet? Educate me!!
