This doesn't seem to happen with monometal bullets equipped with stress relief grooves, and following the hypothesis above, they simply do not cause high pressures of examples with no stress grooves......
I wouldn't rely on "grooves" in the full calibre width of the bullet one little bit. Instead the best monometal bullet examples have RAISED bands with the 'shank' being sub calibre. The rifling can groove the rainsed bands without excessive pressure or displacement. The grooves hardly change it at all. My hypothesis.
Interesting you observed the OSR on a bolt action Weatherby. Usually the reports of it are on much thinner barrelled multi barrel firearms.
