According to the Indiana DNR, the following are legal:
Rifles with pistol cartridges that fire a bullet of .357-inch diameter or larger; have a minimum case length of 1.16 inches; and have a maximum case length of 1.625 inches are legal to use only during the deer firearms season. Some cartridges legal for deer hunting include the 357 Magnum, 38-40 Winchester, 41 Magnum, 41 Special, 44 Magnum, 44 Special, 44-40 Winchester, 45 Colt, 454 Casull, 475 Linebaugh, 480 Ruger, 50 Action Express, and 500 S&W.
I'd take a look at the Marlin lever action 1894, chambered in 44 Magnum. If semi-autos are legal in IN, Ruger makes a nice, handy 44 mag.
