I personally can shoot my 44 Mag double action faster and more accurately than I can my single action 357 Mag but I like and practice with the double action and don't with my single action so there is that. I will take the guy that practices with his 357 Mag 686 in bear country over the guy the thinks his 500 JRH single-action means he doesn't have too any day of the week and twice on bruin-attack day.
Why to bear threads always turn into this?
Who thinks that? There are a couple of factors that we need to assume in making comparisons and one is the shooters' marksmanship. Another is shot placement. I don't know anyone who hunts with revolvers and carries them regularly afield who doesn't practice -- a lot.
They turn into "this" because many weigh in without real knowledge.
