Assuming that you are referring to a .44 Magnum handgun for hunting game. In the instance of hunting something similar as a reindeer, the heavier bullet would be of little/no advantage. However, if hunting something larger i.e., Elk (European "Moose"), big bears, etc., then the heavier bullet would be deemed by many shooters to be better in terms of better penetration in heavier muscles, bones.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
