The Hornady Bullet Seating Die for 8x57mm JS Mauser (Hornady part no. 044116) is machined specifically for the .323-inch bullet diameter used in the JS variant of this classic military and sporting cartridge, an important distinction from the earlier, smaller-bore 8x57mm J chambering. Handloaders working with 8x57mm JS Mauser rifles need a seating die that matches the correct bullet diameter for the cartridge, and Hornady builds this die to deliver consistent, repeatable seating depth round after round for that specific chambering.

Key Specifications

• Built specifically for the 8x57mm JS Mauser cartridge.
