In my 16" PRI, 24.1 grn TAC pushing a Nosler 77 w/cann @~2650 = BH 5.56 77 SMK (retail MK262). In my experience ammo of this type is MOAish...
FWIW that same load in my Centurion 16" recce clocks @~ 2750.
I'll have to dig my TAC numbers out, but at around 2700 fps, it was around moa.. nothing to brag about though.
That load (MK262/clones) sacrifices accuracy for terminal/long range performance to some degree IMO.
Is ~2700 FPS out of a 16" barrel about average for mk262 variants?
More like 2650 with typical 5.56 chambers.
I spoke with a ramshot guy. The 2 1lb containers I have are energetic, ~ +1%. The next 8lb lot is -4% so if your 24.1 is slower it could be from a less energetic lot. Load to velocity. An 18" should probably be ~2750 but a more accurate load will likely be less. These loads (~MK262) sacrifice accuracy for performance, plus loading this hot is hard on brass...
