All older ammunition using primers containing potassium compounds that break down into residual potassium chloride salts are considered to be corrosive.
Collecting and firing WW I and WW II era firearms is popular, and along with vintage firearms, vintage ammunition is available in large quantities. Older ammunition from Germany, Russia, Turkey, most Eastern European countries, and also China, were made using corrosive priming compounds. Stored properly, this ammunition is safe to fire, and is often still considered premium quality. Being corrosive only means that you will need to clean your firearm to remove the corrosive salts residue before it can cause damage ( 24 hours or sooner in humid climates). The salts are soluble in water, so soapy water or even Windex will suffice, followed by your regular powder solvent.
As for Brown Bear Ammunition: it is a commercially produced product from the Russian Bernaul Armory. All of their current ammo is Non Corrosive, as is Russian ammunition from the Tula Armory (Tulammo, and Wolf Brand) . Any older Russian commercial ammunition can possible be corrosively primed, so if you have some that is over 10 years old, it may not hurt to clean up as corrosive, just to be safe.
Brown Bear Ammo, in 7.62 x 54mm available for sale today, is NOT corrosive.
