I note that Louis has some factory 9x56mm cartridges and am sure many other members have some as well. For those that do, could they possibly do some measurements preferably in inches but if not possible, metric is fine and post them for the benefit of all members. Of particular interest are the following dimensions of original factory rounds. Please indicate manufacturer.
1 base at the web not the rim.
2 at .5” from the base of the case
3 outside of neck close to the bullet
4 bullet diameter immediately in front of case mouth.

Thanks to all who can help.
