All three brands of .455 ammo, and a box of commercial Remington-Peters .45 ACP 230-grain ball ammunition, were used in testing the vintage revolvers at a local range. To eliminate human error, a Ransom Rest was employed for the accuracy tests. Bullet speeds were measured with a ProChrono brand digital chronograph positioned 10 feet from the muzzle. Although distances in close-quarter trench combat were probably much shorter, the target was placed at 25 yards.

Commercial .455 Mark II ammunition used in the range tests included Fiocchi, Hornady and Kynoch brands. Also shown are a string-tied 2-pack of military .455 Mark II ammunition, dated 1922 and a World War II box of.455 Mark VI Ammo, both of Canadian manufacture. The front row comprises assorted military & commercial rounds.

For the tests, each revolver was clamped into the Ransom Rest and a dozen rounds were run through the gun to settle it into the grip inserts. Once the revolver was solidly secured in the machine rest, 18 rounds (three cylinders full) of each brand of ammunition were fired in the gun. Accuracy was determined by measuring the extreme spread of each six shot group, center-to-center, and then calculating the three-group averages.
