Well this thread was unexpectedly entertaining..ive said it before, thunderheads have killed alot of deer. But so have rages and bout every other..hey wait a minute..... You asked about toxic heads..all ill say is its a broadhead shaped like a biohazard sign. Will it kill yes..but it smells like a gimmick..idk what it actually smells like tho, prolly like metal or plastic or somethin, but none the less..gimmick in my op
