New Cooper Model 21 in 223 Rem.
I have been working with my new/used Model 21 Cooper to find the best bullet/powder combo. I believe I have. Latest trip to the range with 28gns of W748 behind Sierra 40 gn BK yielded a .117 three shot group @ 100 yds. Picture attached. This is an off the shelf Cooper with a Sightron 36 BR scope
