Just cruising the deer regs about handgun hunting deer. Regulations state that the case length should be over 1.16" and a bullet diameter of over .243. 30 Carbine has case length of 1.29 and a qualifying diamter, so why is it listed as an illegal cartridge for use in a handgun? 32-20 meets those same regulstions, but is listed as illegal. I thought that you could fire rifle cartridges from handguns for deer in IN, just not in rifles.
