Here is a picture. The boys told me they didn't have to remove the thick lump near the neck's base as it caused no trouble with the new chamber.

When using RWS 8x68 brass, the new 9.5 has the same capacity as a .375H&H, or up to 3gr. more if the .375 brass is RP or FED- IIRC.

With 9.5x68 brass made from .375 H&H brass(belts turned to .522"), the capacity is larger by 3gr. average.

.375/06AckleyImproved: 6.5x68S: 9.5x68S: .375H&H Magnum

The9.5x68S appears to not have been fire formed - yet.
