Don't know why you need a .30 cal anything to kill a deer....
I am laughing pretty hard too. But then I am the know nothing idiot that dropped a mule deer into it's shadow at 240 yards with a 22 hornet and a hand swaged 40 gr bullet out of a 14" TC contender. That bullet was swaged using a spent 22 short case for a jacket. If you can hit what your shooting at you don't need a 16 inch gun.
