Well, I imagine a quartering away shot to be one where the far front shoulder is not obstructed by the facing hind leg(ham). If in a 90 degree turn the animal can go from perfectly broadside to facing directly away, then it would be in that 15-45 degree turned range. 0-15 degrees would still be virtually broadside. “Quartering hard” is like that 60 degree realm where you’d need to make contact with the very front of the hind leg to go through the center of chest cavity. That shot selection would be totally up to you but it could also be a second shot if your first hit was poor and needed to get another round into the animal before it’s out of sight. And in a heavily timbered area it is not out of reason to think that it could be your only shot available. This is a completely reasonable hunting scenario and it’s up to the individual to determine if it’s an ethical first shot based off their setup. If I’ve learned anything from this thread it’s that I need to use descriptive words carefully because guys will try and tear anything they disagree with apart and put words in your mouth. Avoid words like “all, every, need” etc . Like professional protesters on the picket lines. Again, I do not condone ass shots! Some of you have said you have faith in match bullets penetrating from that 60 degree angle shot. Thats fine, you likely have more experience using them than I do. I simply don’t have the faith in them that some of you do.
