It's approximately .413" I can't think of any cartridges off the top of my head that use a .413" bullet. the .405 Winchester uses .411, and most of the .40 caliber black powder cartridges with which I'm familiar run from .408 to .412 for their bore diameters.

What is the question related to? If it a proof stamp for caliber, it could be the bore, the grooves or not really 10.5 at all, just near that based on plug gauges.

Probably something like the 10,5X65R Collath aka 10.75X65R Collath. Really need a chamber depth and chamber profile.

Could something like this be re-chambered to a more common and low pressure cartridge?

Nice gun. What is an "Artist's Resale Right"?

About all the other 10.5mm choices are those Teschner short 10.5mm target cartridges less the Beast Miller & Grieß 10.5mm Behemoth.

So how long is the case? What exactly is the bore diameter? Is it a straight wall case? My little Sauer driller wouldn't take a .44 caliber bullet. It turned out to be an 11.15 X65. This is a more common choice than some mentioned here.

Since this is a German rifle, it is likely shown as a 10.5mm rifle because it is marked as such in the proof marks, either directly in mm or in a gauge measurement that translates to 10.5mm. They were marked with the bore (not groove or bullet) as Raimey stated. The actual cartridge's nominal designation could be any one of several different ones, and not necessarily of German origin. To ID the cartridge, a chamber cast will be necessary, together with "slugging" the bore. Rechambering such a rifle is a poor choice, for several reasons, not the least of which would be the need to re-regulate it, even if it could be done safely. A much better idea would be to handload for it, even if you have to make cases and bullets from something else.
