If you have the luxury of a rest shooting while hunting than somewhat lower % shots are more probable. I on the other hand rarely have a rest and never hunt with a firearm in a tree so shooting off hand is imperative to being successful. Now I ask why in gods green earth would you aim for the neck on a broadside shot of what ever distance, this is just foolish and brash. Again last resort this should be considered and factored in with your skill/ability. The one deer I shot last week gave me a face on shot but slightly angled ( I took the shot through the neck angled to the opposite pin as opposed to neck on neck shot) The distance wasn' t a factor, my skill wasn' t a factor, I however took the highest % shot and felt confident if I pulled or missed my mark slightly I would have a vital hit. The result was a deer dropping and not moving again, this was free hand from the sitting position on the ground at approx 150 yards. Off course our deer out here have remarkable body and neck size which can lead to a larger target and room for error on attempting these neck shots. On more than one occasion I have seen deer rattled out and shot in the meat of the neck only to keep coming or stop and just stand there while the hunter drills them proper the second time. I know all about needing to put that animal down and with minimal tracking, I will tell you broken pins is the best and surest shot to take, why would you ever aim for the neck when you have a clean path to the vitals...think like a bowhunter just implement the weapon you are toting![8D]
