In the African Hunting board are several threads on photos of spent bullets. There is one on North Forks. Take a look and you will see why the Barnes in a serious contender for bore busting while the driving band bullets are not.

Maybe your computer skills are up to "stealing" a photo from there? Mine are unfortunately not.

What you will see in the North Fork photos is a true driving band bullet where the shank or body of the bullet is under not only bore diameter but land diameter as well. There is no engraving of the shank or body of the bullet. The only material displaced is the material of the driving bands, and there is sufficient volume between the driving bands to accomodate all of the displaced material.

On the other hand, while the groves of the Barnes appear sufficiently spaced to accomodate displeced material, the shank of the Barnes, above and below the bands is engraved. The material has to go somewhere and some of it appears to go to the sides, but not all. There is compression of the shank as well, I'd bet. And so the real risk of braking solder joints, maybe the reversed rifling issue as well.
