The table (thanks, Bruce) certainly speaks to the lethality of 28s within a reasonable range. I pulled my copy of the Small Bore Shot Gun out and looked to see if there was any clarification for choking 28s or distances at which the guns were targeted -- none that I found. The table in the back lists both the 3/4 and 5/8 oz. loads for the 28 and has percentage of #7 shot in a 30 inch circle at **40 yards** I believe the brochure is from the late 1910s or early 1920s(?).
So is there any proof that "some" (as Muderlak suggests) 28s were patterned
at 30 yards rather than 40? If so, to achieve a full choke pattern (65% using the brochure number) wouldn't the constriction be less than the .022" figure from many published tables? It seems logical to me that it would. And if they did use 30 yards for some pattern testing, when the records say "full choke" (with no pellet count), what might the constriction be? Just curious.
