If the perpetrator survived a shot to the face with #6 shot, they would have a perfect exhibit to display to a sympathetic jury in a civil trial. With #4 Buckshot, the only thing the Plaintiff's lawyer will have to work with are pictures of the body. Which would be more beneficial/less harmful for the Defendant?
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
