in the hope that you could use it someday?
Short time ago I took a leap: guy had some Tula Berdan primers, and while he didn't know if they'd fit the 7.5 cases, they did fit 7.62x54r. Called a friend who did some checking and thought they were the same size, so I grabbed the brick.
Last night I took five cases, deprimed and resized, and primed. These went through my Hornady hand priming tool with no problem, and felt just like boxer primers going into a case when seated. I've loaded those five with the cast-bullet load, and next time I hit the range I'll try them. Looks like this'll let me use that bag of brass I held onto.
Remember, if you want to use berdan cases you have to take the deprime/neck expander piece out of your resizing die, and use some kind of berdan depriming tool to get the old primers out(I've got one of these, and BLEEP! the price has gone up!)
The primers I got are Tula KV-7.62N Large Rifle Primers, Berdan.
Added: should have put this in originally, got them from
