That Turk ammo is a dead-on copy of the Germanicon World War One loading. It has a 154-grain flatbase bullet ahead of a charge of flake powder. The primers are dodgy, though.

I did a test on some of this, unloaded the stuff very carefully and dumped the charges (without bothering to weight them) into fresh-primed commercial cases, seated the military bullets and went to the range with 3 rifles: a Kar 98aZ, a Mauser 1915 Gew '98 and a 'No-name brand" Kar 98b from the von Seekt secret rearmament program in the 1920s. Imagine my shock when ALL THREE rifles started turning in groups WELL UNDER 2 MOA and some of them exactly 1 MOA... with original sights!

Shooting was pleasant and without the nasty kick that you get from those Heavy Ball loadings (which actually were the original anti-Tank loads, BTW).

The 154 bullets are not in those cases very hard, or very deeply, at all. Just insert in the muzzle and one quick and short twist and they are loose and you can pull them with finger-power. You don't even need a puller for these.

Don't bother dropping the charges, either. This stuff shoots quite pleasantly with the original charge levels. I have NO idea why they ever changed!

Hope this helps.
