Thanks guys! I'm not too discouraged, i love the thrill of the hunt, putting one down is a bonus.
bugsnbows you're dead on. Jumping the string would have results in a shot over the back, maybe it was some buck fever.
I'll be back on him this weekend, I'll update this post if I have another sighting or shot. Good luck guys, I'll be shooting after work to figure out if it was equipment (probably not) or nerves.
