Pistol Cartridge Only
As mentioned, the State of Indiana only allows pistol cartridges. You can't use a high powered rifle, i.e. 243, 270, 25-06. The cartridge can't be more the 1.16 inches long. I have a 44mag and shoot the Hornady ammo and it shoots great out to 100 yards. I can drill the center of a pie plate all day long. My wife uses the .44 mag as well and with all the clothes she wears hunting, the recoil is never an issue.
Good luck
