Videos tagged with Sub-caliber Insert

This video demonstrates the unique use of a sub-caliber insert to fire 7.62x51mm NATO rounds from a WW2-era 37mm M3 Anti-Tank Gun. The process involves preparing Hirtenberger ammunition, loading it into the insert, inserting the assembly into the cannon's breech, firing, and then manually extracting the spent casing. This method offers a cost-effective way to train or shoot with historical artillery.
