[Amatikulu]

303 Ball Mk 8 Z Cdn Lot IVI-85 H0103 - Mark 8z indicates the bullet is a boat tail bullet loaded and the cartridge is loaded with a nitrocellulose powder. IVI is Industries Valcartier Industries of Canada and the "-85" indicates the year of manufacture 1985.

Blank 303 LMk5z 16/11/53 - L is a letter used to demarcate a blank round on the headstamp - nitrocellulose loaded and made in 1953

303 D.I.MkVIIz - D.I. is Defense Industries, Montreal. Mark VIIz is nitrocellulose loaded with the standard flat based bullet.

303 Mk7z 1951 - same as above but loaded in 1951 - manufacturer uncertain

Here in the USA the cheapest 303 I find these days is old cordite loaded rounds at 50 cents a round
