A friend picked up a 16x16x unknown rifle caliber by this retailer. It has some type of underlever action. Should I pursue more information on this gun for those interested here?

YES!!
Please take a dial indicator and measure the inside rough
diameter of the rifle barrel
Thanks
Mike

OK will relay and try to get good pics of the proofmarks.

Hope these will do of the Loesche.

I believe the rifle caliber will be a 9.3x72R

12 GAUGE, yes check if a 12 gauge hull will fit the chamber

And I would say the 12 gauge chambers will be shorter than 2 3/4
and should be measured.

So why are the barrels marked 8.8mm?

12 ga 2 3/4" fit each chamber nicely.

What do the proofmarks tell you Skeet?

Hal,
My security won't allow me to open the photos, saying the "halbucket" has Malware in it,so I couldn't look at the proofs. A 2 3/4" shell will chamber in the short chamber, because the crimp hasn't folded out.Once fired, the crimp will fold into the barrel and constrict it.Whether this is harmful or not is a big point of discussion. If the barrels are marked 8.8 mm, this is the bore diameter, not the groove or bullet diameter.The actual groove diameter in different 9.3x72Rs vary a great deal.Since I couldn't see the proofs, I didn't see if the case length was shown.There were several different 9.3 mm cartridges with different case lengths.

When in doubt do a chamber casting.

The 8.8 indicates a 9.3 bullet in the 8.8 rifling
As KY Jon says a chamber cast is a great idea

The fact that unfired 2 3/4 ammo fits the chamber is no
indication of proper chamber length, measure!

I am pleased you discovered it was indeed a 12 gauge
