500-

My comments are without any personal experience as I have unfortunately never hunted Buff.I have no experience with solids on any animal other than seeing a 350 pnd boar shot with FMJ 7.62's.It took the animal forever to expire.

I voiced the conclusion that solids have less put down killing ability after reading other African hunters opinions, and one of several discussions and opinions will be noted--

The shots refered to are desired broadside shots. For frontal shots I would absolutely agree and think solids would have a more prdictable path to the brain or spine.Thats the neat thing about Doubles with a soft/solid combo-you can brain 'em with a solid or whack 'em broadside with a soft.
