They think the back boring reduces some of the recoil because of the larger barrel diameter reducing some friction. It would be interesting to chronograph 00 B out of a VCS and non-VCS barrel. Reduced recoil rounds might be a less expensive option.
Both gives you the recoil of a smaller caliber rifle.

And it's always fun to show off the work that Hans Vang developed.
