After bowhunting a gun just seems like cheating....... especially if you are Esshup!!!
Unfortunately we cannot use most centerfire rifle caliber guns here in Indiana for deer hunting. The brass has to be no longer than 1.8" (brass only - no projectile) and the bullet has to be at least .357" diameter.
I use my Savage Muzzleloader in .45 caliber for the gun hunting season here.
