Hi,

Interesting subject that inspired me to do some checking:

I have compared a present-day Sellier and Bellot 9mm 115gr FMJ with a 1917 DWM-made round.

Case length: 19.05 MM
Tip length: 10.95 MM
Total length:30 MM

Weight and dimensions are a perfect match. Not strange, since S&B was one of the 9mm suppliers in the luger-days, using the LKM production code.

A 1940 winchester drawing of the 9mm shell shows:
Case length: 0.754" = 19.1516 MM
Total length: 1.169" = 29.6926 MM

Both cases are well over 19MM long, a clear indication of their reliability in lugers. Lengths of over 19.17 MM generally are too much. Everything between 19.00MM and 19.17MM should feed and extract properly.

I would be interested in the exact sizes of 115gr 9mm walmart winchester to see if the present day versions are still the same size as the 1940 ones.
