RE: Marlin lever action 44 mag for deer?
This may have happened with this particular doe. It could have happened with this gun, a 30-30, the 44 mag you are asking about or any gun.
But it you think that the general result of shooting a 35 Whelen at a deer is "the gun literally flips the deer on their backs and they are dead on impact" I believe you will find that this is not going to be the case.
