I switched from a 30/06 last year to a old school 308 SA,,, of course I load hot 180gr boolitz for the hunting season here in the North for mostly Elk, Moose and lots of Deer,,, then tap it cool for the off season predator control thing...
I came off the Magnum diet 7 years ago with just as many successful harvests as in the past,,, l'm more focused on shot placement then ever before thanks to the F Class shooting sports...
Find what works for you and get at it,,, that's what really counts,,, sight in a go kill stuff... Nothingness more fun than filling the freezer with good times I'd say.
