Sorry Calfed, I was getting too involved again.

Summarizing:
The GP11 cartridge is amazingly accurate in the G96/11 (also in the K31icon, according to reports).
The bullet is not cylindrical, but shows a distinct taper.
Measuring the taper requires some care.
This taper could well be an important accuracy factor.
Commercial 308 bullets will work, 307 could be better.
I wish I could get some of those GP11 bullets and try them in a "normal" 300/308 rifle.

And thanks for the link - a very interesting contribution.
