I think Bryce M. Townsley nailed the article. If his objective was to stir up some lively debate. These days I could not care less what cartridge the rifle I am using is chambered in. Long as I know where it hits at 50yards and 100yards and I have the ability to put it there its all good as far as I am concerned. Not really concerned what Jack O'Connor did or didn't do either. I have messed up shots with lots of different rifles and can generally say that the cartridge was not to blame for any of them. I have been aware of any limitations there may be so it is all on me. It follows then that I take the credit for any perfect kills I have made and not put it down to a particular round. Put any rifle in my hands and send me out and I will be more than happy. Even an AK47or a 270.
