i made my first kill sat, i have a few questions maybe some one can answer for me. my shot placement was great, even surprised me, but my arrow did not pass through. it was a 15 yard shot, no bone was hit, so why didn't it pass through? i use the muzzy bone crusher broad heads, my arrow stuck in his side as he ran off, no blood trail. it was kinda scary trying to find him with nothing to look for. i found him though. my bow is set at 65 pounds with a 80% let off. am i shooting to light? i'd like to have all shots "pass through" can any one help?
