I have been trying to find the max (without pushing it) pressure, as measured by feet per second, out of the end of a 16 inch barrel of an AR 15 that shoots 223 and 556.
I have chronoed a 16 and a 20 inch barrel and, of course, I noticed a difference in FPS out of each one. The longer giving me the most FPS.
Is the max really a function of the nature and quality of each individual chamber and barrel? Yesterday one of my shots registered over 3100 FPS a significant increase over all the others and it got me to wondering what the max FPS was, if it can be generalized.
Again I am NOT interested in pushing the FPS just being careful.
