The five digits before before the forward slash:

• First two digits (digits 1 and 2): Prepend a ‘3’ in front of the digits to get muzzle Velocity in meters per second. Example: If first two digits are 27, then the muzzle velocity is 327 meters per second.
• The last two digits (digits 4 and 5): Year of production code. 54 = 2019, 55 = 2020, etc.

The six digits after the forward slash is the actual lot number (assumed to increment sequentially).
