I've come full circle with the 270 and elk.

I used a 270 on my first half dozen elk and it worked fine, but I got bit by the magnum-craze in the early 1990's and bought a 300 Win Mag. Used the 300 Win for the next 10 years or so and it worked fine for elk.

I realized I wasn't shooting the 300 nearly as much and enjoying the recoil less and less. I switched back to the 270 about 10 years ago and have been packing it ever since.

Thinking back over things, I really can't remember where the 300 was a deal changer or where elk died any quicker than when I shot them with a 270.
