And/Or your arrows are too light weight! What is the draw weight of the bow and the grain weight of the arrows you are shooting?
I suspect Murray would design a bow for hunters, one that is supposed to shoot a minimum of 10 grains of arrow weight for every pound of draw weight. He don't strike me as the type to be designing bows for wimpy range shooters and their anorexic knittng needles with fletching!
My everyday shooter is 50# draw sinew backed osage that rattles my teeth with the spot shooting 425 grain needles. When I went to 700 grain ash arrows it tamed down terrifically but doesn't seem to be more than just a little slower. Some day I will have to get chrony readings on arrows of different weights just to see.
