Well i have a quick story and feel that the blades are to blame,to make a long story short i had a good shot on a six point saturday(my first deer after hunting archery for 6 years)plus i used a rattle bag,grunts,and can call,to get this deer to its 30 yard shot(that was exciting itself,i guess those hunting videos payed off)after hitting the deer at 30 yards with a good side stance the deer turned around and walked back to where it showed up,stopping a few times to put its head down and snort what i thought was blood out of its nostrills,so i new i got a good hit(so i thought)Well i drew another SPITFIRE blade to see if i could get another hit but it faded away at 45 yards,well after giving it 30 minutes or so i decided to get out of the stand to look for the arrow,i found the arrow that was snapped off about 3 inches down from the blade,it did not go the whole way through the deer though i did not see any blood so i decided to go to the spot i seen him stop and there was blood with bubbles in it so i new i hit lung,well i tracked it after waiting an hour or so giving him time to at least time to lay down and expire,because of his slow progression,well it ended up me trailing for about 250 yards before loosing the trail,so i decided to give him another 2 or 3 hours to pick up on it again,i went back in after two hours and picked up a trail again of more bubbly blood but lighter in color almost white and trailed this for i know at least another 150 yards but then it stopped,i walked off from the last sign at least 150 more yards for 2.5 hours to find nothing i checked in all heavy brush to see if he was down but nothing,well i gave it all i had with tracking with 2 people,well i feel the shot was good but i feel only one lung was hit and i also feel the blade did not open,seeing the blood was not alot,any comments or suggestions on this might help me feel better,seeing my knees still hurt from crawling on the ground looking for signs.Thanks.
