OK, using anything for deer other than the 270 is a waste of time. The 270 is far and away the best pure deer cartridge on this planet. Load any good 130 grain bullet and never even consider any inferior calibers like the 243 and 30-06 and 7MM Mag.

There That opinion should stir things up a bit. Honestly with todays excellent bullets, No deer would ever know the diference between the 25-06 and the 300 RUM. Or anything in between. Sorry I can't stupe to the 243.
