thanks for the reply Mike -

check out this site from one of the BBS forum members -

I reference the site because I understand there is a rise in big game airgun hunting in the US. I just want to make sure its humane & ethical. From what I keep reading, large bore PCP airguns are capable of shooting some very heavy( 225+ grain ) pointed pellets around 600fps. In close enough range, a head shot would be deadly ( I think ? )

Thats why I hope folks who are familiar with this airgun technology will write in and add some comments
