RE: Went on first hog hunt! Have questions!
To answer the origional question. Yes there are some 30-06's out there with iron sights. Excellent choice of calibers by the way. Browning makes a lever action in 30-06 and you might find an old Remington pump action.
A fun gun to shoot in 30-06 is an M-1 Garand. You can wear a hog out with that one.
