I don't see the this-vs-that point between theses 2 cartridges. Both are equally capable of dropping any
critter on the face of the earth with a well placed shot & using the right boolit for the job.
The scenarios that folks encounter though while hunting game, along with individual mindset and ability as
well as the endless variables that go with the hunt such as weather, physical condition of the hunter etc. etc.,
are what really make the difference between success and failure. A flubbed shot with an 8 bore is similar
to one with a 6.5....escaped game, a long track to recover game, or a mauling on your end.
