If the gun has a half moon cutout in the front reciever ring to allow the bullet tips to clear you have one of the older small ring turks and you might want to stay away from the very maximum loads in reloading manuals such as Speer that load the 8mm to its full European power specification.

If it is 7.90-7.92 you have the larger barrel groove diameter and slugging is not needed. Turkish Mausers have the bore diameter stamped right on the barrel in front of the reciever under the handguard.

Lee, RCBS, Hornady, etc) resize the case neck to a 0.317" ID or a 0.323" ID?Ģ) Does any newly made brass come with the 0.323" ID necks?Ģ) Were Turkish Mausers made in 0.317" ID, 0.323" ID, or both? If they are both, should I worry about measuring the actual ID before selecting a bullet for him to reload?Īlso, I would appreciate any advice and/or reloading resources for the 8x57 in a Mauser. Interestingly enough, he also has some seemingly brand-new R-P 8mm Mauser cases, and the ID on the case necks is 0.317" which corresponds to the older diameter.ġ) Would a "modern" sizing die (i.e. If I understand it correctly, that is the "newer" 8x57 diameter that came out post-WWII. In his pile of reloading stuff, he has 3 different lots of bullets, all of which measure a 0.323" diameter. I've never loaded for 8x57, and after doing some research on the round, I'm more confused now that ever. A buddy of mine just inherited a Turkish Mauser and a bunch of reloading equipment, and he has turned to me to help him reload for it.
