I didnt even think about going down to the ole lumberyard and checking down there.. I thought about shooting the broadheads w/o the washers but i tried that a while back with the shockwaves with an older bow, and the blades went thru my inserts and chipped my arrows a little.. Ill have to go down by the hardware store tomorrow after school and check them out.. Did you like these broadheads? Im shooting a Diamond Machete and only plan on taking turkeys with them so i figured they could atleast get the job done. I have yet to take a turkey with my bow, so i cannot wait till spring.Thanks for your help!
