A relative owns and operates a gunshop here locally. He's sold quite a few Tikka T3s over the past 5 years and has recently found customers purchasing the Ruger American rifles. The Tikka T3s have always been tack drivers, but the cost of T3s has been steadily going up. The feedback he's getting on the Ruger Amarican is that they're shooting bug holes. They seem to shoot way good for such an economical rifle. He's sold a number of the .22 WMR versions also, and those customers have also been claiming very good accuracy. So Ruger is doing something right.
Accurate rifles require quality barrels, and it seems Ruger is now mass producing quality hammer-forged barrels for their American rifles, as Beretta has been doing with their Tikkas for quite a few years now. Once a company gets the hammer forging equipment running well, they seem to mass produce high quality barrels, very CONSISTENTLY. And their cost per barrel must be pretty minimal in order to be able to sell the completed rifles for such low prices.
If they Beretta and Ruger ever start producing aftermarket hammer-forged barrels, the competition for the custom barrel manufacturers will get pretty stiff. Based on the Tikka T3s I own and the ones others I know own, I'd be content buying an an aftermarket Tikka barrel for a custom rifle
build. And I suspect there could be a 50% or greater cost savings over the custom aftermarket barrels.
