The banded (or triple-shock)Barnes bullets I checked had undersize bands that reduced pressure in my 7mm rifle.
: It is interesting that the round-ball nose of the Barnes penetrated less - can't argue with evidence, though.
: I'd expect the flat-nose might not girate as much while penetrating. As well, it will havea cutting effect, rather than spreading the tissue as far as the round nose bullets.
: Seyfried noted that the .416" Barnes Solids he shot into Cape Buffalo exited from any angle, but made fairly wide holes through the meat and tissue. His premise what that the bases girated as they travelled though. Evidence being the collapsed shanks of .458 Winchester bullets that had too-thin jackets.
: I do like to see photos of "result' bullets with good data.
: I am quite sure I wouldn't personally shoot a solid, 'soild' through thin double rifle barrels joined by solder. That's got to be hard on them, but then, with a heavy steel jacket solid, is there less 'stress'?
