I am not a gunsmith. But I will explain the best I can. I believe they call the process "line boring". They actually put the cylinder in the revolver then drill the cylinder. So they are aligning the cylinder up perfectly with the bore of the revolver. This is just one of the custom features they do when manufacturing the revolvers. You are basically buying a custom revolver. They are even a few steps above the Performance Center S&W's.
The 454 was their flagship cartridge. that is why so many 454's.
I had a Field Grade 454. It was a real dandy. 100 yard+ shooter with no problems.
Overall they are just a well made piece of American engineering.
The Ruger revolvers are also good revolvers. But you are not really comparing apples to apples. You are comparing custom manufacturing to mass production. Tom.
