RE: 22 mag deer
22mag. is NOT a deer cartridge. I suspect, I hope, that you simply misunderstood your instructor. First off, I'd bet the 22mag. does not meet the legal requirements of any
Game & Fish Dept. for minimum calibur/cartridge for deer hunting. Yes, it will kill a deer,
but is way underpowered/too small to do the job properly.
Might be used for head shots by poachers, though [:@]
