what round did the bar use
On that note, the M1941 Johnson can use M1 Ball or M2 Ball, and the M1 Garand cannot shoot the M1 Ball without endangering the M1 Garand and the shooter. M2 Ball was designed for the M1 Garand, but can be fired in the Browning Machine Guns, the BAR, the 1903/1903A1-A3-A4, and the M1917.
