I did the 303 based Australian cartridges this weekend but there are some questions that I hope one of the Australian forum members can assist with. In a 1991 ECRA newsletter there was a reply by Bruce Morgan to a query from another collector and he listed some, or I assume most of the 303 variations from Australia. One such cartridge was the 303/22 Sprinter with a case length of 52mm.Specimen below.
Another specimen was the .303/22 Falcon, otherwise known as the “full length” 56mm round with specimen below
My questions are regarding the following two cartridges. The first has a 52mm case length but that is different from the 303/22 Wasp that was listed with a 44mm case length, unless that was a mistake in the original newsletter:
The second specimen has a 55mm case length and the shoulder length is different at 43mm as opposed the 44.7mm for the full length (56mm) case.
Thanks in advance
