Re "perhaps I might need a charge stopper "

A charge stopper is a FMJ and that's about it.
It is the only way to "guarantee" straight line pnetration
through bone, boss, horn etc etc

That's why I always load the last 1 or 2 rounds in a Mag
as FMJ's - either coming at you or going away, you need
a FMJ.
