Looking for some info re 50 cal rounds. From the Big Bore site:
"Trapper-Do you have a pic of the 12.7 x 108 mm long soviet round.Apicture of it next to 50 BMG
would be nice.And the base dimensions.I need to know the base diameter?"

I can't find any comparison pics or dimensions. Can anyone help?
Regards,

Hi there,
I measured a few specimens from my collection and averaged the base diameter at .855. Hope that helps.

If you go to the 'Heavy Machine Gun Cartridges' link in my ammunition photo gallery: http://www.quarry.nildram.co.uk/tankammo.html

You'll see both of them illustrated there.
