Tested/chrono'd some 62gr bthp's and 77 gr smk's for the 11.5" ar and shot for the 1st time the 300blk 10.5" build and 50 test loads of 147gr fmj's and 125gr smk's. Very impressed with accuracy(.690" group with 2moa red dot)and velocity(2084fps)from the BA 300blk barrel and 125gr smk so far. Have some 125 gr sst's and barnes black tips 110gr' on the agenda to load. Going to be a nice little 100 yrd hunting rig.
