Here are some more. From the May 1903 Baltimore Arms Co. catalogue --



From the 1905 Philadelphia Arms Co. catalogue --



None of the shotgun manufactures seem to recommend the barn burner 3 1/2 drams of bulk smokeless pushing 1 1/4 ounces of shot --



or 28-grains of Infallible or Ballistite also pushing 1 1/4 ounces of shot --



Interesting thing about that Remington hang-tag that lists 24 grains of Infallible pushing 1 1/4 ounce of shot from a 2 5/8 inch UMC Nitro Club shell is that the UMC catalogues of the era list such a load as only coming in the 2 3/4 inch shell. While early on one could get 1 1/4 ounce loads in the 2 5/8 inch 12-gauge shell, during the first decade of the 20th Century our ammunition manufactures phased them out and from then on only offered 1 and 1 1/8 ounce loads in the 2 5/8 inch 12-gauge shell. You had to go to 2 3/4 inch or longer for the 1 1/4 ounce loads.
