    .50 Spennymore

    I have four variations of the .50 Spennymoore. All from a friend in the UK. These types of exps were produced between 1942 and 1945 I have three SR 1942 cases and one SR 44 case with a split neck. I have been looking for a replacement case.

    There's 9 or 10 variations of these projectiles, so I have 5 or 6 to go.....................

    Top to Bottom

    SR 1942 50 / Solid Steel AP - Twin driving bands
    SR 1942 50 / Solid Steel AP - Slightly different driving band than the one below it
    SR 1942 50 / Solid Steel AP
    SR 44 50 / Brass Fused HE or HEI

    Are they placed on 12,7x99 shellcases?

    The name of the town where the factory was located is actually spelled Spennymoor.

    Thanks Falcon, I think I knew that, just forgot.

    I received what was supposed to be a .50 Spennymoor projectile in the mail today. It may very well be, but it is different from the others I have. In the attached photo, the projectile on the top is a Spennymoor, the center is what I received today and on the bottom is a US .60 Cal. I included a US .60 Cal projectile to compare the construction of a known US projectile to the center projectile.

    The gas check/driving band dia - Spennymoor is 13.6mm, the center projectile is 13.5mm, the US .60 is 15.35mm

    The projectile dia - Spennymoor is 12.67mm, the center projectile is 13.13mm, the US .60 is 14.9mm

    The total length - Spennymoor is 52.84mm, the center projectile is 53.36mm, the US .60 is 69.37mm

    The center projectile also has a 3mm hole drilled in the bottom of the gas check.

    Any ideas??????
