My Utah general season archery elk hunts are coming in a little over a month and I'm really jiving with a 53# @ 27" longbow. I'm shooting a 550 grain arrow through the chrono at about 148 fps. That almost seems comically slow to me, but I do hunt out of a tree stand over water that I have killed two elk off of which were both right around the 15 yard mark. I don't think I'll need a laser trajectory for that. I'm shooting it real well and it's throwing a bare shaft real well. Broadhead will be a Magnus stinger 2 blade sharpened to a scalpel.
