Hi and thank you for a good reply.

Yes, the Collath did make in a style for them self, good or bad.

I now learned that they had two 8*72R calibers, the other was with narrowed powder space. They also had a 9.3*72R with the same narrowed powder space. And some more interesting calibers....

But, back to the 8*72R.

I am do my own loading yes, but brass may not be so easy to find, in a caliber like these. First have to find out if it is a Collath caliber or a Brenneke or even a Sauer caliber.

I will try and find out when the gun, drilling, is made and come back with some more information.
