Meaning, a "safe" mono bullet is a bullet that has an undersized shank and bands that allow the displacement of the metal impacted by the lands. BUT.......that bullet must fit the GUN.

I will agree with that.

I worry that the bullet first shown below has such thick bands that the barrel must bulge to let the bullet pass, and the grooves simply reduce contact area rather than serving as a location to receive the material displaced by the rifling lands.



This bullet appears better able to engrave as the driving bands are thin and the materials is easily displaced into the grooves behind the thin bands.
