Could somebody make a short synthesis of the primers used by these 4 compagnies?
Something like, for each company, a board separate in two families:
- rifle, carbine, pistol, revolver (all together)
And for each of these two families : berdan or boxer , open or closed primer, diameter of the primer, and designation
I am sure they are experts on this forum about US primers, and this short synthesis will save me a lot of time.
