Early this year I shot a doe with my Tekan II heads. Made a huge hole and she went like 60 yards and dies with a huge blood trail. Well....this weekend shot my second doe at 15 yards through one lung and smack dab right through the hart and a complete pass though with the arrow sticking in the ground. The Tekan didn't open up!!! She only went like 30 yards but no blood what so ever, there was snow on the ground toooo.! Looks like someone shot her with a rifle the hole was soooo small. Anyone else have this same problems with the Tekan II's
