A load that worked well for me:

Rifle: 16″ 1:7 twist medium contour barrel AR-15, 5.56x45mm NATO chamber

Load: (work up, be safe, use at own risk, etc.)
LC 09 brass
CCI No. 41 primer
23.8 gr Ramshot TAC
2.255″ COAL
RMR 75 gr 3GH (LOT 2)
Avg Vel. 2,610 fps (10 shots)
32 fps Extreme Spread
8 shot group 0.33 MOA (actual MOA, not iphy)

I might try 23.7 and 23.9 gr of TAC as I just stumbled on to 23.8 gr of TAC.

I have no idea what the terminal ballistic performance is so I won\’t speak to hunting suitability.
