I believe it was BP but am working in Norway this week, the catalogue is at home, I will try to remember to look it up

If BP it is obsolete calibre for the rifle, (VERY arguable for the shotgun) the list is only guidance, depends where you live/what your local firearms dept. of police try to interpret the actual law

Huvius - the Fraser looked good IIRC ( looked at so much) did not check the bores, I see it is no longer for sale? Did you get it?.
