I have been doing some research into sporting guns around 1700-1750 when wing or bird shooting started to be very popular using smoothbore flintlock guns of the time. Although buck and ball was used as well as shot in trade guns overseas like the new world of the time, i was wondering what size shot was available during this time period and what was commonly used back then Today we have a choice in the shotgun world using shot sizes from BB to 12, just wondering what they had available back then.
