In a 2007-2008 dated pamphlet on the Finnish defence industry I have found an image of Raikka made 12GA LTL loads and the box says “+1 care shot” which appears to be a red plastic case.
Anybody to tell what exactly a “care shot is”? Something that contains oil or some other material?
I assume the propellant in the LTL cartridges is no blackpowder and the primers would be mercury-free anyways.
