"Hi Fred", Well, first off, let me explain to you why I choose to take advantage of this fairly new rule which is in effect ONLY during "Firearm" season in Indiana... I couldn't hit a bull in the butt at 10 feet with my shotgun loaded with slugs, so years ago, right when muzzleloaders became legal during "firearms" season, I built a T/C Renegade from kit form, with scope, sling and all, just for deer hunting. It is deadly accurate and has taken several (I'd like to brag and say many) deer... But as you know, re-loading for a follow up shot, especially when your fanny is up a tree is a joke... So, when they came out and said you could carry "more than one type", I elected to carry my .41 Magnum, or my .357 Magnum along. I also have a legal black powder single shot, but have not shot it enough to be comfortable with yet... I'm going to include a link to the regulations, but to save you a bunch of looking, I cut and pasted the pertinent part below... here is the link:
