ShrinkMd, yes I have, 70 rounds of 8mm57 for $4.70. This ammo outran my 30/06 ammo, but, it was corrosive, the cases split, necks split, and it out ran my 30/06 and the primers were corrosive. to fix that I used 30/06 military cases I purchased at a flea market in Buck Horn NC, 1,400 cases for .01 cent each, $14.00 dollars. Because I am a fan of forming dies I formed 1,000 8mm57 cases from the 30/06 once fired military cases, then, ordered the Hornady cam lock bullet puller, I wore that thing out 4 times, it was like they had it more than I did or I spent more time waiting for parts than I did using it. Now I have the RCBS Colet type puller.
Anyhow, the Turkish ammo is hot, @*$ hot, I measured the powder in random cases, 49 grains, because this stuff out ran my 30/06 ammo I reduced the load by 4 grains, at 45 grains the reloaded ammo shot like Romanian ammo.
I have purchased 8 pound jugs of pull down powder from Pat’s Tumbler/reloading in Ohio, I just picked up 16 pounds of surplus powder last week, what is the difference between pull down powder, I pull it down, they pull it down.

At the time 8mm57 cases were expensive in the Remington green and orange box.
Cases were .01 cent each, each case had a 30 cal dirt dobber (black wasp) not ready to hatch, anyhow, the wife opened the garage one day and they left, like a black cloud and she was not happy.
Head space? When I form cases for a chamber I form them to fit the chamber, no fire forming required.
