You guys are aware that all rifle cartridges with bullets .243 diameter and larger but with a case length of 3" or less are now legal for deer hunting on private land in Indiana, right?
Some of those rounds are legal on public land too. Most if in a pistol like the AR15 pistol are legal, and also some are considered pistol rounds like the 458 socom and can be used legally on public land in rifle configuration. I know some use the 300 B.O. in a pistol, others use the 458 socom in a rifle.
