Hi, i have reloaded for that bullet for my savage 223, 1 in 7 twist, 26 inch barrel bolt gun. It does shoot very well for me, per my load data from 100 yard tests, Varget 20g=2558fps, 1/4 moa. 22.3g=2720fps, 1/4moa.
RE-15 20g=2423fps, 1moa, 22.5g=2719fps, 1/4moa,. These were 3 shot groups and i didnt see any overpressure signs, hope this helps. OH, forgot to mention, the COAL for these loads was 2.326 inches.
