I agree with Bonanza that this disucssion is indeed bordering on the absurd. I don't understand the concept of trying to force a superb short and medium range tool (a Double Rifle) into something that it can be in theory, but in practice will always be less than ideal, a long range weapon. A double must be regulated to allow both barrels to shoot to the same or close to the same point of impact. Take a lighter double (30-06) and regulate it for 300 yds, and then it becomes useless at 100 or 150 as the point of aim is no longer there.

Of course, you can always 'regulate' a single barrel by using a scope and sighting one of the two barrels to shoot accurately at 300 or 400yds. So what, you now have a single barrel, single shot rifle.

And are you really going to shoot a bear at 300yds? Not me, and not something a competent guide will permit.

If you want to go after elk, etc or shoot at 300+ yards, use a bolt. We seem to be deluding ourselves by ignoring real life and spending inordinate time speculating about making doubles do what they were never intended to do, and what they will always be compromised in accomplishing.
