First of all: no load data I could find published or even discussed in other forums mentioned using military brass and Tula primers. So I will not discuss load data here, just the process.
I don't know how to post pictures and so I didn't take any this time.
But, I figured out how to re-use the really nice GP11 7.5x55 brass. With household stuff.
I used a "high quality" 1/8" drill bit to barely pierce the primer cup, off center. No Harbor Freight bits, go buy you a pack of DeWalts. Don't go too deep, you'll hit the anvil - which is made into the case in a Berdan primed case.
Then, take a small nail (I think I used a 4d) and simply insert the point into the hole you made, and pry the primer out.
The GP11s were crimped in. If you drill your hole against one of the three crimps, then you are not prying directly against the other two and they'll slip out easily.
If you can stick the bit just right and stop it as soon as the cup is pierced, it'll pry it out too; but nails are cheaper than drill bits and I didn't want to chance breaking a bit.
I wore out two nails doing about 50 cases. I nicked a few anvils too; will see if those go off.
Graf's has Tula berdan primers and they fit just right in the GP11s.
I know, it's a lot of trouble to save a 45 cent piece of brass. And I've heard that water depriming works but I didn't have anything that would fit right in the case neck. Plus, it's cold and I didn't want to be slopping around in water in cold weather.
To resize, I used the Lee Collet die with the little aluminum cap milled out and the needle bearing pin pulled out; so that the mandrel could be there for the case neck to squeeze against but it wouldn't bottom out in the case.
Works good for me. YMMV.
