As said above, people don't replace the RPR barrel because it's inferior, they replace them because they are shot out or simply worn to the point accuracy fades. What more is the Savage going to give you? Some of these rounds are hot, venerable barrel killers. 308 will last for years and 20k, 6mmCM will give you 3k and a season of shooting. Just the way it is.Any thoughts on purchasing the Savage rather than the Ruger and then not having to replace the barrel?
Both rifles are simple to replace the barrels, you just have to decide what you want for features. A Savage in a hot caliber won't last any longer than a RPR in the same caliber.
