zrex...I usually don't respond to these type posts on the grounds that I might incrimidate myself....
There is nothing wrong with a brain shot on any animal, and it's not just poachers that use it...I have killed several deer with a shot to the head with a .22...Let me point out it is perfectly legal in my state to do so and before I was a deer hunter I was a squirrel hunter and only took head shots with a .22....If you have the skills to take it, it works...
I have had 2 occasions that I remember to do the same with my .243, no problem...
I will point out, I grew up hunting and in the country...I could walk out of my back yard with my .22 and hunt...I had also seen my dad dispach hogs when we butcherd them with a .22...I am not advocating anyone else doing so, but a .22 to the brain is lethal...
