Can anyone identify this .32 Rimfire adaptor?
I thought it was a .303 as all measurements fit except for the shoulder length.
Made from brass with a steel firing pin off-set to hit the rim.
Rim is 0.526". Rim thickness is 0.060". Base is 0.460". Mouth is 0.393".
Inside mouth to clear the rimfire is 0.323". Case length is 1.880" (48mm).
A .303 is approx 46.2mm to the end of the shoulder so much shorter.
Does it look home-made or factory made like a Marble? Difficult to say.
