European and eastern military or surplus ammunition often uses corrosive or slightly-corrosive Berdan primers because they work reliably even under severe conditions, and have a longer storage life than the non-corrosive type primers currently in use. Modern Boxer primers are almost always non-corrosive and non-mercuric.
The BEAR series is a line of hunting ammunition. The cartridges use lead-cored Full Metal Jacketed, Soft-Point (Semi-Jacketed), or Hollow Point bullets, have steel cases with Berdan primers, and use a non-corrosive propellant and primers. The sub-brands differ only in the protective coating used on the cartridge case.
Unlike the USGI ammo, which has non-corrosive Boxer primers, it has corrosive Berdan primers. The cases have longitudinal scratches along the sides, like they have been reloaded. The bullet has a black sealant at its base and the primer has a clear pinkish-red sealant rather than an opaque red sealant. They come packed in 50-round cartons.
The original French-made military ammunition tends to be scarce in the United States and is often corrosive and always Berdan-primed. The pressure is rated at around 40,000 CUP or about 295 MPa (42,800 psi). The original military brass is highly prone to head separation when reloaded above 40,000 CUP.
Most surplus ammunition is steel-cased and uses Berdan primers, which effectively hinders its use for handloading. However, with the increased popularity of surplus Eastern-bloc Mosin–Nagant, SVT-40, and PSL rifles in the United States, Boxer-primed ammunition and unfired cases are increasingly available; these cases take large rifle primers.
Berdan and Boxer primers are used in centerfire cartridges; the primers differ in construction. Various priming mixtures have been used in different sized primers to effect prompt ignition of the powder charge. Particles with relatively high heat capacity are required to promptly ignite smokeless powder deterrent coatings. Some priming ...
It had a 10 g (154.3 gr) Semi-Armor-Piercing bullet with a copper jacket and mild steel core, corrosive VT stick propellant, and a Berdan-primed steel case with a green lacquer coating. The case mouth and primer pocket were sealed with a red sealant.
The third line listed the model of primer (Zdh, or zundhuetchen), the date of manufacture, and the manufacturer; an "X" between the primer type and date of manufacture indicated it was a type of primer with a low mercury content.
