i'm goofing off at work and want to run something up a flagpole and see if it flies lol With help of a co-worker measuring to the front of the riser i get 28 1/2 inches so i'll use 29 inch arrows. i'm going to go carbon and strictly shoot to go hunting. I want to use 110 grain muzzy broadheads. I figure at 6gr per pound with tip i should be using 400gr arrows is this correct? oh yeah the bow is 60lbs dw
