    .222 RMAI (Rem Mag Ackley Improved) in a 16” Contender!

    Does anyone have any data on reloading the .223Rem Mag Ackley Imp, in a 16” contender, with 50&55gr bullets? Mike Bellm brilliantly fixed a poorly chambered 223 bbl with this solution, but the data is scarce, to only a few loads he used to push 50’s to 3000 fps in 16”. There’s lots if 223AI data...
