With bullet performance these days hunting and killing has changed drastically in the last 50 years. You hear about the debates of old from the 50's 60's 70's and today about which is better blah blah blah. I say find a gun that you are confident with and know your range and limitations while hunting and get out and enjoy the woods. I happen to have a .270 WSM and really do enjoy that rifle, I have never hesitated shooting anything with it. I did shoot my bull last year with a .280 Ackley Improved, and after messing around with that cartridge last summer I really like it as well as far as performance!
