Whether it has been applied or not there have been advances in metallurgy and technology over the last 100 yrs.

It would seem that the technology is available to manufacture a Double with lighter components, acceptable durability,faster lock time and a stronger action. In theory such guns could weigh the same as bolt guns with one barrel but have the 2nd shot capabilty that Doubles enjoy.Recoil should be no worse than a similar barrel bolt gun of the same weight.

Are the lighter weight 9.3's and Merkel 141's accomplishing this? Are they more desirable over their predecessors? Sounds like these calibers may be becoming a better mousetrap.

Is there a lack of similar applied technology used for Big Doubles or avoidance of techno applications due to weight requirements for recoil management?? Are we making better stronger Big Doubles today or are they inferior to their predecessors?
