some interesting Chrono data from the 9MM AR platform

I am a member of the M14 forum which was also acquired by the anti gun conglomerate who took over NYF. They have a lot of knowledgeable members on there about everything M14/ M1A. I did run across one poster who tested 77 different 9mm cartridges through his 9mm AR and posted the results.
figured @Willjr75 would be interested if no one else was.

Cool info. Its nice to see the extra velocity even considering the fast burning powder.

Wow, that's interesting. I'm surprised at those setback issues, is that a carbine specific thing? Also what does "ES" mean?

extreme spread - the difference between highest and lowest velocities.
