This link has got info about the Turk 8mm ammo. The top picture in the link is of what you'll most commonly encounter (most of the stuff I've seen had 1930's headstamps). If you happen to get ahold of some of this stuff, I'd recommend shooting it in your Mauser (my younger brother's Yugo M48A has had several hundred rounds of Turk ammo shot through it with no ill effects) but don't shoot it in your FN-49. I've read and heard several reports of parts breakage when this ammo is shot in a non-bolt-action firearm such as an FN-49, G43, Hakim, or MG-42.
