I don't completely agree with that. I would not consider myself a failure or that I failed in the hunt if I let an animal walk because say he is too far from me or at a bad angle. Failure (or unsuccessful) has a negative connotation implied with it, and in cases mentioned above (which will happen more often then not with the type of weapons we are choosing), I would considerit positive that I let the animal walk. My hunting skills and preparation has brought me to this situation, however factors outside of my control are now at work.Now if an animal is within my range, I took my shot, missed, or wounded the animal, I would consider this a failed hunt. I would even go as far as saying a failed hunt could occur if my arrow did not go where I intended it to go (not deflected) but I was still able to recover the animal. I have had this happen in the past and did feel like a failure.
