I believe you are 100% correct that most people want to make their DR a tack driver and in all reality cannot shoot it offhand to it's potential. But IMO this holds true to most rifles, be they be a bolt or DR, especially in the magnum calibers.

I was mainly curious as to the regulation of the barrels, having one barrel spinning the bullet one way and the other barrel spinning the bullet the other way. I read a post either here or on AR by Ray A. I believe, that DR's were regulated by shooting the right barrel first, then the left? I was curious if the spinning of the bullets in different directions had ny affect on how the rifle was regulated? Just curious as I have never heard of a DR set up that way.
