I get it. I measured the chamber. Call it 936. With all due respect, what does this tell me? I mean specific to my chamber, 936. Does that say anything about using old Winchester brass or new industrial plastic with the belt sized down?

When you say paper, do you mean plastic? Because I dont see any paper cases in 8 anywhere.

It seems I have no choice but to buy the brass (or plastic) and measure the hull ID. Then buy the wads or punches. It has little to do with my gun. That is unless I split all the cases due to 936. Can someone tell me will factory old Winchester brass fit 936?
