Well I just herd back from a fella whos bow I just tuned and put new strings on it, fletched and cut his arrows. He called and said he fired, his bow with the new arrow, anyways his first shot his arrow broke in half about 1 inch past the vanes towards the point so only about 3 inches from the nock. WHAT happend here, these are brande new maxima arrows, 250 spine, his bow is set at 48lbs and 27 inch draw so they should of been fine. I told him not to shoot until I look at it, his peep cam flying out as well so he pretty much must of dry fired the bow.
