What makes ammunition so valuable? A lot of things, but its high amount of copper content ranks right up there. That’s why many Russian manufacturers avoid using copper where they’re able, and why Wolf’s 7.62x54r ammo is poised to help you fire your Mosin-Nagant all day but still stay under budget.
This round’s case has the appearance of brass, and it does indeed contain copper to help it feed and extract with greater reliability. The case still contains a lot of economical steel, however, so you shouldn’t make any plans that involve handloading it. The Berdan primers Wolf uses are a little most cost-effective to manufacture than the Boxer variety. They still spark up reliably, and they are non-corrosive.
This round’s 148 grain FMJ projectile features a bimetal jacket. Just like its case, the bullet’s bimetal jacket features a barrel-friendly exterior layer of copper drawn over a budget-friendly layer of steel. Such a bullet is plenty hard enough to resist deformation, but it will not pass many indoor ranges’ magnet tests.
