Shotgun shell length


#1

I am trying to find out when the 3 inch and 3 1/2 inch shotgun shells were introduced. I have been going through Stadt’s “Winchester Shotguns and Shotshells” and Iverson’s “The Shotshell in the United States” but can not find a date for their introduction. Can anyone assist? Does anyone have any referenes? Thanks.

Hi!
I suppose your question is about 12 gauge.
And also about US shells:

Remington all brass (up to 3 9/16): 1877
Remington paper (3) : 1877

UMC paper (up to 3 1/4) : 1880
UMC all brass (3) : 1876;
UMC all brass (3 1/4) : 1882;

USC Co paper: (up to 3 1/4) : 1882

Winchester paper (up to 3 1/4) : 1879
