To be honest,GMMAT, I'm a bit surprised by a lot of the responses. By all accounts, my Grim Reapers shouldn't penetrate as well as the rage because they open "jack-knife" style. Since I started bowhunting last year, I've killed 9 deer with them, and every one has been a "COMPLETE" pass through (the "COMPLETE" is added for annika).
I'm shooting a little heavier arrows - they weigh in at 520 grains total weight. 70# @ 29.5" @ 270 fps. There has to be something to the heavier arrow. Oh, and for LT, they're GT 7595's- larger diameter arrows that pass through wonderfully.
Sorry... forgot what my own draw length was.[:@]
