OK: My Ar build is almost done this is what i have a DPMS 223/1-8 SS 24 inch upper and a Stag lower now i need too find some loads for this rifle using 77, 69 gr. MK and 55 gr MK Sierra bullets then will start looking for some Berger loads.

For 55gr try H335 somewhere around 24.5gr.
For 69gr try Varget. 25.3gr is supposed to be the accuracy load.
For 77gr also use Varget. I'm using 23.7gr of that.
