Greg,

Thats a tough one man...i will RARELY shoot at deer without stopping them...i think ive done it once and i ended up gettin the back of the lungs luckily. I know that you had a bad experience with gruting at him to stop him, but its usually the best thing to do.

Dont beat yourself up too bad. It didnt sound like too bad of a shot. I think you should give him some time for sure and get back after him. From what you have said it sounds like he should bed up and expire. We can only hope anyway...

Good Luck!
