I think that is what we are all trying to do with the main problem being swaging the body of a 5.7x28 down far enough to finish the outside to .242 without breaking the case off at the case head/wall junction. At least that's been my biggest problem and although I have a few more ideas to try my move from AK to MT is taking all my time. I'm forced to put this on a back burner for a while.
