Actually, I know a couple of handicapped guys who hunt Antelope with a .50
They use .30 bullets Saboted to .50
Their grandsons drive them to the top of a ridge, then they sit in their wheel-chair and wait. When the game comes in range they bag it.
Load up and drive to the downed game.
Not the way I want to hunt, but so far I still have a choice.
But given the way my back is deteriorating, I may be doing the same in a couple more years.
The crew I hunt with were just talking about that a few weeks ago, if there are tree stands available with wheelchair "lifts" for when we all get older. That's really cool that your friends don't let their handicap get in the way of enjoying the great outdoors.
