Precision 223 Load

One load I’ve found that has been MOA or better for 10 shots from ARs and bolt guns that have the twist to handle it is the 77 TMK, 25-27 grains of LVR powder lit by CCI450’s in a 223.

The reason for the variance in charge is the cases but I’ve been using 26.5 for quite a long time in my Dillon 550 I don’t even mess with the charge anymore. In an 18” upper it’ll run about 2775 FPS and man it’s a killer combo for anything I’d use an AR or 223 for.
