Did any aftermaket 10 round mags come about for the K31?
Not that I know of. Stgw57 mags cannot be easily adapted, as they don't fit the opening in the K31 receiver.
There were a couple of more or less clumsy attempts to make a "Frankenstein monster" by joining the K31 mag top with a Stgw57 body, but nothing even close to market-ready.

Thanks for letting me know.

As for the ammo and cases, Norma are making them, but they are costly, as hell!
The rifles has gained some popularity in Europe, over the past couple of years and the demand for mil-surp ammo is high, but they are quite hard to find.
One of my buddies has one, and he has almost given up long range shooting, in favour for this ol' sucker.

As you said, Norma brass is excellent, but insanely expensive.
Recently, Sellier & Bellot started manufacturing 7.5x55; factory ammo is not as good as ordnance GP11, but the brass is good, certainly better than Partizan.

I acquired a K31 back when they were selling for ~150. It had a "card" with the last soldier's information; sent a letter but did not receive a response
This year I installed an old Bausch and Lomb 4200 6-24X using a no drill mount ST Marie.

It does well with Berger Bullets and 43 Gr of 4895; 2570 fps, SD 6.1 Brass: Grafs; OAL 3.01

As others have commented, once the barrel warms up the dispersion increases.

I know this isn't the for-sale section, but I figure it'd be a real 'stars lined up' moment for anyone to catch it on this site's PX. I have taken the Weaver k4w and mount off of my rifle and if anyone is interested in either, feel free to PM me.
