220 Russian
As I understand it the 220 Russian case was designed and is exclusively manufactured by Lapua, based on the Soviet 7.62 x39
I emailed and received a drawing from Namm Lapua Oy, dd. 2002-02-04, now on a dead hard disk, though I did print a hard copy.
It gave the following dimensions in mm, Rim 11.2, Head 11.16, length to neck at 9.2 dia - 28.35, shoulder/neck 38.2, case length 38.7, shoulder inclusive angle 43 degrees.
These dimensions are slightly different than shown in the CIP drawing and others, and it does surprise me CIP and Lapua are different as I am sure Lapua are a member/associate of CIP
