Hello All,
This is a basic question that you experienced collectors could help with.
In both Hoggs book on cartridges and Macks book on cartridge dimensions, both list many Lancaster case types.
These are usually straight rimmed cases that seem to be variations of many of our current shotshell cases.
Were Lancaster cases proprietary, early developments in ammunition or were they something else.
Your explanation on the background of Lancaster cases would be helpful.
Thanks,
Brian
