Some illegal rifle cartridges for deer hunting are the .30-30 Winchester, .444 Marlin and .45-70 Govt.
it is not against the law to fire a 45-70 pistol. It has to be a length of 1.16 inches long with no maximum case length provided. It is illegal in a rifle because you have a max case length of 1.625. I know because I checked with the authorities. You can check them out in the hunting and trapping guide.
and yes you can use a 45-70 in a pistol to take deer in IN...you can also use a .270 out of a pistol iffin ya wanna
