7.92x33

Any sites on loads/dimensions/components for this cal?

For case dimensions check out... www. reloadbench.com, they have a case drawing for it.
As for load I used Hornady 125gr .323" (8mm) fmj with 22gr of IMR 4198. I was also using re-sized .308 brass but you can now get commercially made brass, the proper size,
