The caliber doesn't reload any differently from any other rimless bottle necked rifle cartridge.
The die sets are expensive at retail. Sometimes a set can be snagged for a good price off one of the auction sites.

I got along for many years reloading it w/ 8x57 dies and a shell holder that I thinned down to allow the case to be pushed into the die a touch further.
That little amount was enough to push the shoulder back on standard 8x57 brass.
The cases also needed a bit of trimming and in my instance the bases needed reducing in diameter a few .000".

Once the brass was made up it chambered in my rifle and fire formed.
From there I neck sized only for reloading it.
I've even used the 32acp seater die body as a simple neck sizer die for this and the 8X57.
Works nicely, no expander necessary and you can see what you're doing better.

The base reduction is a one time only thing. Some rifles don't need it. Perhaps using a different brand of brass it wouldn't have. I used Remington.

I use .323d bullets, groove diameters can vary I'm told but both my 1908's are the same.

After using this method for years I did find a near new set of RCBS 8x56 M/S dies for I think it was $35 in a 4sale listing on a gun forum.

There's always a way to get them up and running.

I've seen a few re-chambered to standard 8x57Mauser. The cartridges are so close, I don't know if the rotor would need work.
They always work perfectly when laying there for sale on a gunshow table!
