I HAVE IN MY POSSESION A 22 CHEETAH MK1 REAMER AND DIES ARE COMING.
it is basicaly a 308 BR brass necked down to 22 cal. I think I can just use 243 or 308 brass. It will do around 4,300 FPS or 1000 FPS faster than my 223 I have a couple 22-250 barrels that have the throat starting to go and Im going to rechamber them with this and use them on a screw in barrel build.
its a barrel burner but it will be fun and fast an flat. a 1-7 twist with 100 GR 223 bullets would really reach out there

when built it will likely have the fastest MV of any AK ever built slightly fater than the 17-223 I think.
