I do not for one second doubt that George won that competion with said barrel and said round count.
That said, as an innocent bystander
and student of science, how is it that two different cartridges of same caliber and capacity have such huge differences in historical/predicted barrel life? Being a holder of a couple of science degrees and generally disposed to that sort of thinking, it greatly puzzles me.
As a student of science, I also know that many variables can confuse the apparent result and so it is necessary to exercise controls over the experiment.
Based on my limited knowledge of the shooting sports and laws of nature, I would say one, there are always exceptions to the rule and two, the observed outcomes resulting from the laws of nature are hard to deny.
Bottom line..... there is usually no free lunch
If you like the 6.5 WSM, go for it. but if you are of the opinion that you are going to get 3000 rounds of high performance accuracy, be prepared to be disappointed.
I am going the 6.5 WSM route and completely understand what's expected. That said. I'm hedging my bets on a treatment that may increase my expectations.... but am prepared for whatever
