However it explicitly states
“
ammunition of a relevant kind” means ammunition for a firearm of a relevant kind;
“
firearm of a relevant kind” means a firearm other than a shot gun, an air weapon or a firearm chambered for rim-fire ammunition.
Clearly the idea is only a person with a FAC with a relevant firearm/ammunition can buy metallic primers, eg. .223 small rifle primers.
Educate me
Apart from usual shotgun cartridges a lot of “shotguns” is chambered in rifle or pistol cartridges (loaded with blanks or shot for sale on a SGC).
please give an example available , thanks.
