M-4 MV
« on: June 13, 2007, 03:19:20 AM »
Has anybody done any chronograph work shooting the commerical M-4?  Would be interested in seeing data for the shorter barrel.

Thanks,

Turk

I,ve done quite a bit of chrono work with my M4orgery. My experience has been roughly 125 fps less than the 20" gun. This is not written in stone, sometimes it varies with bullet weights. Some of the loads were less than 100 fps. This is with a 16" bbl., not a 14".
