An older friend of mine approaching 70 years of age made the statement that with some of the new bullets today he believes his 243 will kill as effectively the 270 he's hunted with for more than 30 years. Maybe this thread should be will the 243 replace the 270 in the lower 48?

As far as the 223 being used to kill deer more than the 243......I really don't believe the idea of that is too far fetched by any means. Look on any survival websight and the 223 is the deer rifle of choice....Not to mention I think it is probably one of the number one selling rifles in the united states today and I'm pretty sure most who are buying a 223 are not preparing for varmint season.
