You haven't provided any "real evidence" there, just theory.

For example, with double rifles, bore and groove "measurements" will or should always be taken into account and addressed, regardless of what bullet type is being used, not just with mono's. It is a standard proceedure with DR reloading.

"Material", where has it been proven that any particular mono bullet alloy is any safer than another, where OSR is concerned?

"Design"?
Well, you must be believing what some bullet manufacturers are telling you regarding the wonders of their particular brand of banded monos, while at the same time refuting the claims made by other mono bullet manufacturers like Barnes.

Your opinion seems to be that banded mono's made by certain companies, which are made from a certain material, and have correct dimensions for the double rifle barrels they are to be shot in, are safe and will not cause OSR or rib joint damage.
Is there any evidence to support this?
