Obturate in the typically meant context of expanding to fill the bore under pressure may be a hold over from the old BP days.

Great example of what I call the “Not everything in one Shooting discipline extrapolates to the others”.
I can assure you that 92/6/2 bullets listed as .358 but actually measuring .356 will lead the shit out of a Gp100 in under 50 rounds. Like bullets hit the target sideways lead. Hard isn’t always the answer.
