I'm gonna call bull (literally) on the ridiculously heavy arrows. Heavier arrows will help, but there's no free lunch. Trajectory needs some consideration as well. If I were to go on an elk hunt, I would choose Axis/FMJ's arrows and heavy duty cut on contact broadhead like a Muzzy Phantom without the bleeders. My 25" Axis obssession arrows and 100gr. Silverflames weigh a total 360 grains. That's a touch over 7 grains per pound.
