MLH I think a few of the guys have tried to give you good advice and obviously you aren't welcoming it. Shot placement is always a personal issue based on the accuracy of the gun, the skill of the shooter, target size and the distance. There isn't a seasoned person on these boards that hasn't learned through experience...some times the hard way. You have been told what many think and are holding to your own methods. I can safely say a head shot wouldn't be something I would brag about and around this campfire isn't normally well received as ethical.
I'll add this paste of rule 8 just to make my feelings clear.

Rule 8. Do not engage in “flame-wars” or excessive exchange of confrontational postings. Debate is important, but users should not try to “pick a fight” with one another.
