safe the pics on my computer, turn them right and post again with https://picr.de/.

don't live in lancaster, hundred years ago the "Lancaster" case was the center fire shotshell in contrast to the "Lefaucheux" or pinfire shell.

what cartridges was the remington lee chambered beside of the .30 Krag what is a perfect simple cartridge for reloading today I presume because die sets and brass are allways available.
the bullet caliber is .308 (?) so a lot of bullets could be used.
