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.
