The 7.62x54R cartridge is probably most noted in the United States as being Mosin Nagant ammo, although, there are several other rifles that put this round to use as well. The 54R cartridge has been around since 1891 and performs excellently, which is why it is still around today. With a large powder load, and big bullet, it is a fun and impressive round to shoot.
This particular load from Tula Ammo is made with a steel casing. This keeps the costs low, so that it can be sold for a great sale price. The steel cases are polymer coat to help prevent corrosion. The primers used in this bulk ammo are non-corrosive Berdan primers.
The Tulammo 7.62x54R uses a 148-grain projectile and is rated for a velocity of 2785 feet per second.
