RE: Exotic and Hog
Good avice all around. Axis venison is terrific; not only the best game, but just about the best meat I've ever eaten, especially the backstraps (butterflied, seasoned,then grilled).
Your .30-06 will do fine; I shoot a Savage in .30-06 and it hasn't let me down yet.
If you're shooting the hog for meat, skip the bigger ones and try to stay with the under-100-pound hogs. Their meat is more tender and flavorful, in my opinion. Getting 150 pounds of nasty-tasting pork is a lot worse than 30 pounds of something you'll enjoy eating.
Good luck!
