John Roberts,
I am not arguing that the 25 ACP is suitable for deer, only that with correct placement it will kill one. Being from southern Mississippi I'm pretty sure that if you ask around, you will find out that they have frequently been killed with 22 LR (less powerful than 25ACP) or maybe 22short in your area. None of these are suitable but, at least 25 ACP (with expanding bullet) is legal in Alabama, being centerfire. I can remember reading other people's opinion that 25-35, even 30-30 are not suitable for deer. I think you would agree they will kill a deer under the right conditions, while under other conditions they might not be suitable.
