The United States produced ammunition for the thousands of Mosin Nagant rifles ordered by the Russians. Along with standard Ball cartridges, Proof rounds were also made. The Remington version of the proof load had a blackened brass case, while the Winchester version used a tinned case. Along with Remington, Western cartridge company and US Cartridge company had contracts to produce ammunition for the Russians. In 1940, Winchester-Western produced 7.62x54R for a military contract, this time for Finland. World War I era Remington ammunition was packaged in 20 round boxes with a simple ink stamp showing caliber and date.
