Michael McIntosh, in his book on AH Fox, describes the Super Fox as having .740 bores in 12GA, with a .048 inch constriction at the muzzle. The forcing cone was 3/4" long with an oblique taper. The choke cone was 4-1/2 inches long, with a straight, untapered section of bore the last inch at the muzzles. They were mostly chambered 2-3/4 inch, but could be chambered 3 inch. The 20 gauge Super fox's choke cone was 3-1/2 inches and standard constriction was .033". McIitosh didn't mention the 20 gauge bore, so maybe it was .615. These guns were made for the then-new Olin Super-X cartridge, in 12 gauge a 1-3/8 ounce charge of copper plated #4 shot. If one were to attempt to select or build a gun to put a lot of shot into a small group, using plastic wads and nickel plated shot for turkey, what would the gun's bore look like? Some Super Foxes were capable of putting 90% of the shot into a 30" circle at 40 yards. What configuration of bore/choke is out there now, and what are you folks' thoughts about how you would configure such a gun today? What would chambers, forcing cones and chokes look like today? Whose screw chokes work best? Which ammunition would you use? Which guns would best suit this goal?

No. The early Super-X loads were only with "special chilled shot." The Super-X loads in 12- and 20-gauge put up in Western's 2 3/4-inch FIELD shell were introduced in 1922. In late 1922 they added the 16-gauge Super-X load put up in the 2 9/16-inch FIELD shell. By 1924 they added the .410-bore Super-X load and the 12-gauge 3-inch Super-X load put up in Western's high brass RECORD shell.



The Lubaloy shot Super-X loads, put up in the high brass RECORD shell were introduced in the February 1, 1929 price list.

Interesting that in those days they were able to turn out .410 loads that much cheaper than 12 bore cartridges.
