Having previously owned a 416 Rigby, I agree with you as far as that goes. Some of my reasoning in going for the Taylor is that I already have a lot of the bits I need to complete it barring a barrel,& dies etc will be cheaper for the Taylor than another Rigby, being aware of the forthcoming (?) 416 Ruger, I figure that a Ruger chamber should clean up a Taylor chamber but not a Remington one without setting back the barrel so in the short term the Taylor gets my nod, with a Ruger if &/or when they get more common & popular. I believe that careful load development with the correct choice of powders should nullify the pressure concerns that the Rigby was designed to address. 75grs of ADI2208/Varget behind a 400 gr bullet should see me right.
