While doing barrel comparisons is beyond my means, except when I change brands from the one that I just wore out, I pay attention to what big budget shooters, that are doing well in competition are using. Recently an extremely reliable source told me that one of the top shooters in short ranger took delivery of 150 barrels at a major match. With that level of commitment and budget, he could be shooting anything that he wants, and can easily afford to buy five of each if that is what he wants. I also listen to gunsmiths who build for top shooters, whose reputations depend on the successes of their clients. It is not that I need this information very often, but when a new shooter, or someone building a top line custom hunting rifle asks me a question, I like to be able to give them a reliable and informed answer.
