Like Butch says it's all in the hands of the beholder. If it makes you feel good shoot it but the most used barrel in short range benchrest nowadays is a Krieger.I doubt it. If it’s a good barrel they tend to shoot good and I’m not sure how much the other stuff matters like groves, or cut vs button rifling. My most accurate barrel is a cut rifling 4 grove krieger barrel and it is very easy to clean usually only requiring a few wet patches before they start to come out completely white but I’m positive there’s a 6 grove shilen or hart barrel that’s as accurate or more accurate than mine but maybe they would take a little bit longer to clean that I’m really not sure about.
