There's absolutely no reason for someone shooting a modern compound at 50lbs to shoot a 500gr arrow. None. That's way beyond any gains in kinetic energy to be gotten and that arrow will drop like a friggin' rock. No thanks.
Actually, you're wrong one both accounts. Going from 340 to a 500 gr arrow on a 50# BT Equalizer (Is that what you shoot??), you'd gain 5ft/# of KE. 280 gr to 500 gr, you pick up nearly 9ft/#, and almost 50% of the momentum!!!! Don't get me wrong, I'm not saying that you should shoot a 500gr arrow, but if you really want the most "efficiency" out of your bow, you'll do better upping the arrow weight, than shooting a light near IBO arrow.
EDIT: those numbers were also based on a 28" draw, dropping the DL changes it significantly I should note, and that's using OT2, which I know over-estimates speed a little.
No, I'm not
. Most of the KE gained is going from 250grains to 400grains (5ft lbs). After 400grains, the gains slow significantly, gaining just 2.31ftlbs. Going over 500 grains, I start lose KE in very small amounts. Couple that with a rainbow trajectory and it's just not worth it. And "efficiency" does not kill a deer. A well place shot does that.
FYI: The speeds OT2 displays for BT Equalizer are incorrect. It's about 23fps slower than what it should be.
