Anybody have the CIP drawing for this round laying about? I'm specifically looking for rim diameter. Thanks.

Gary:

As drawn by Kynoch, max rim diameter is .572", max rim thickness is .060", and max base diameter is .517".

Here are current standard CIP dimensions for the flanged cartridges standardized by CIP.

Current CIP dimensions for the .375 Flanged Magnum are the same as the Kynoch drawing, except for rim diameter, which CIP has at .565" instead of .572". CIP min chamber rim diameter is .582", so brass made to max Kynoch rim diameter should chamber.

400....THANKS! I just mic'd 2 different pieces of brass and got rim dia of .5625 (Rigby) and .5695 (H&H)....so the .565 is in the middle. Both rounds were fired with no problems, but I was a bit concerned when i saw that much difference.
Thanks for the post.
