This video details the Austro-Hungarian Army's modification of captured Russian Mosin Nagant rifles during WWI. These rifles were rechambered for the 8x50mm Rimmed cartridge, primarily for rear-echelon troops. The process involved cutting new chambers and recalibrating sights, often without re-barreling, leading to squeeze-boring of bullets. Several companies, including OEWG and the main Austrian artillery workshop (AF), performed these conversions.
