For Standard Velocity Only

[Drew Hause]

The DOM of the guns may correlate to Western Cartridge Co.’s ‘Super-X Field’ (12g) introduced in 1922.
The Peters Cartridge Co. named their similar load ‘High Velocity’.
Remington's Kleanbore ‘Nitro Express Extra Long Range’ boxes were marked “3 3/4 Drs. Equiv.”
Western Cartridge Co. never marked the Super-X ‘Field’ or ‘Record’ boxes with “Dr. Eq.” stating only “Maximum Load”. It is presumed that 12g ‘Super-X Field’ 2 3/4” 1 1/4 oz. was also 3 3/4 Drams Equiv. or 1330 fps.

The 2 9/16" 16g Super-X with 1 1/8 oz. of shot was introduced in 1923. I don't know the Dr.Eq. The Super Speed 1 1/8 oz. load was marked 3 Dr.Eq.
