today at a local gunshow i picked up a box (500) CIL No. 4B shotshell primers without battery cups, it says its for any brand and any gauge of shotshell. they do not have battery cups on them so they look just like a rifle/pistol primer just bigger and with a anvil that sticks out a little bit at the bottom.
but how would i load them?
