The requested specification fields are included. When exact ballistic information is not publicly verifiable or requires direct confirmation from the manufacturer, fields are left blank to avoid inventing figures.

To obtain precise values, consult the official technical datasheet for the lot or contact PRVI Partizan PPU support, where measured velocities and exact bullet weights are recorded per reference and production batch.

In practical shooting, group consistency and terminal performance depend on projectile geometry, propellant charge and barrel length. In absence of verified measurements for this exact reference, the entry provides verifiable items and avoids unconfirmed assertions.

Performance, recommended uses and handling tips

The 7 x 57 139-SP cartridges are suitable for big-game hunting and precision shooting at moderate ranges, provided the user confirms firearm compatibility. The Prvi bullet and case combination aims for a stable trajectory and controlled terminal effects.

To optimize results, perform accuracy testing in the specific firearm before field use. Checking compatibility with barrel length and testing multiple lots can reduce POI shifts between batches.

For hunting, it is advisable to verify expansion and weight retention through field trials or independent test data when available. Store ammunition in original packaging, in a dry place and at stable temperatures to preserve ballistic properties.

Safety, storage and compliance

Handling ammunition requires adherence to local regulations and basic safety practices. Use approved containers for transport, store away from children and keep away from heat sources.

Before purchase and use, verify storage and carrying legality under your local laws. PRVI Partizan supplies ammunition under industrial standards, but compliance responsibility falls to the end user.

For bulk purchases, long-term storage or professional use, request lot certification and supplier storage conditions to ensure traceability and operational safety.
