I don't want to sound like a complete amateur, but what role does the brace height on a bow play? I always see that is one of the main numbers advertised on bow websites. Is it like the axle length where it's just telling you the height or does it affect something like fps? Also any input on a direction for what I should look at for my next bow would be appreciated. I purchased a used PSE Brute a few years ago and have enjoyed it but it maxed out at 57lbs (brought it to Scheels and Cabelas and they both told me that's all this bow can go too). 57 lbs is fine for deer hunting and I was told it would be fine for elk, but when I took my elk this last fall, I was ashamed at how it preformed and what the elk had to go through before it died. I will blame my arrows as well, but once again the Scheels bow manager assured me that he used the same arrows to hunt elk and they would be fine (Beman ICS Hunter Elite 400) First shot grazed an artery so loss of blood allowed me to push it til it didn't have the blood to move. 4/5 Arrows snapped on impact shooting just behind the front shoulder, didn't hit shoulder bone, could have been rib bones, standing 10 yards away. Killing shot at 10 yards, made it 10 inches deep. That compared to my hunting buddy that shoots a Hoyt Carbon Defiant at 80lbs and Easton FMJ arrows that went through the front shoulder blade on his elk and halfway out the other side on the same hunt. So next hunt I want better, thinner arrows for penetration and a bow that can go up to 65-70 lbs. Any suggestions?
