Arrow weight

[Bonecollector]

When you calculate KE, speed is factored 2x into the equation, thus it IS more important.
Step back and think about this: there is no "knock-down" power in an arrow". We weight them in grains!
Accuracy and arrow QUALITY are key. IMHO

I have had a pass through on elk everytime I have hit one broadside with my set up, and I shoot just regular Gold tip arrows. I shoot a 340 grain arrow with 100 grain slick tricks out of a 332 fps bow with a 30 inch draw. Granted, my actual speed is somewhere in the 305-310 range. I know my arrows are not as near as heavy as some, but my experience shows that I dont need any more weight. Plus, I like having the exra speed to keep my arrows from dropping as much further out. I would rather have a flat shooting arrow and be accurate as I can be...

I wouldnt add too much weight that causes you to lose too much speed. Broadheads will affect your pentration just as much as adding weight in my humble opinion.
