8x57 and 8x57J

[mallc]

1. What's the different in these two caliber please?

2. Does anyone have a lite load for a Gew88?

3. Does anyone cast lead for this round?

Thanks,
Scott

8x57J uses .318 diameter bullets for the older unaltered 1888 Mauser, and the 8x57 designation is used for the .323 diameter commercial ammo.

Here's some interesting information.

I don't have any data for loads, but did find that SAAMI registration of the 8x57j .318" 1888 Mauser is 35,000 psi.
You might be able to find a Trailboss load with a cast bullet.

Properly, the 7.92x57J and the 7.92x57JS are the .318 and .323, respectively. The "J" is really a gothic I, from Infanterie. The S is for the "spitz geschoss" or spitzer for the pointed versus round nosed bullet. The German cursive is attached.
