Sorry for the delay, spot on bowDrawn, I would like to know the gr weight of your arrow. We have punched a lot of elk and big bone structured critters and arrow weight is very important to the end results in my personal opinion, for whatever that's worth...LOL
I have always been a fan of a little more weight on the arrow than just going for speed. Your selection on broadheads seems right on, both Vicki & I have shot some BIG moose with lower kinetic energy than you are shooting and had pass thru's using the NAP HellRazors, 100 gr. We really like that head! I can tell you with your set up and draw length you will have NO problem taking out the boilermaker on your 1st elk. Hope this helps and we are pulling for you this fall...
