I've killed more elk than most, and I know what a 243 will do and won't do--when anything else in needed, I'll just grab . . . .
So what do you grab for when the 243 is in your hands and you figure out that it "won't do" the job. Your dick?
When everything else is equal, there ain't enough diff ballistically between the 270 and 7RM
Bullet selection, bullet weight, bore size, and case capacity all in the 7 mags favor. Sure the 270 is good . . . just not as good.
Why grab the 7RM over the 270? For the same reasons you grab the 270 over the 243.
