Problem is nine million of them think they are people.

I do have the information regarding the general dimensions of the 378
family. However, what I am looking for are the following which corresponds
to CIP dimension notation standards ...
f (thickness of base foot)
E (height of base excluding belt)
delta angle (angle to belt from extractor notch)
beta angle (angle from rim to foot)
e min (minimum extractor grove thickness)
All the other dimensions are readily available.

Just the shell and bullets. All the rest are rifle specs.
