The 7.62x54r tends to be an affordable round and many opt to simply purchase commercial ammo instead of reloading, although the cartridge can be hand loaded with a lighter load in some cases. If using military surplus, the shells shouldn’t be reloaded. These rounds typically use Berdan primers, which result in corrosion on the cartridge and is therefore not safe for handloading. Prvi does make a boxer primer that can be used instead.
