Yesterday I ran 30 rounds of M.E.N. M193 through a chronograph, and I was disappointed with the results. I ran the rounds through my 16" Daniel Defense M4V7 which has a mid-length gas system, and I used a Caldwell G2 Ballistic Precision chronograph set up 15' from the muzzle to time the rounds. Here are my results:
As you can see these rounds had an average speed of 2,867 fps, with a low of 2,770 and a high of 2,943 fps. That's a spread of 173 fps between the slowest & fastest rounds. Given that M.E.N.'s published velocity for this round is 3,248 fps I expected I would see 3,000 fps as my average velocity with less deviation between the slowest & fastest rounds. What are your thoughts?
