Does sombody know more about this bulletshell (what is Z and DI).
.303 British manufactured in 1943
DI = Defence industries, Canada
Z = Nitrocellulose Powder (as opposed to Cordite)
Also, all DI production was with Boxer Primer ( non corrosive) Cases, annealed brass for rifle calibres, and quality ammo. ( better than similar Cordite loads by other makers.
Just for completeness: VII = mark VII ball (175 grain bullet).
I’m still reloading and shooting with WWII Canadian made .303 British cases.
In Belgium with metal detector
