Heading to ID in Sept. for elk. I'll be using my new Centaur Triple Carbon Elite t/d. 46# @28 and I'm drawing a tad over 27"s. I'll be shooting a GT Nugent blem 400, 31"s with a 50gr insert and a 175gr Simmons Tiger Shark, FOC about 20%.
I've been corresponding with Basinboy (Corey) who took a nice elk last year using basically the same setup as mine and he buried an arrow into that animal up to the fletching.
So to answer your question, your bow is more than adequate for what you'll be hunting.
