I have very little experience in fire forming cases but I am thinking you would want to start with at least a middle of the road charge to properly expand and fire form the brass unless the jamming to the lands provides enough pressure on its own to properly fire form the case at starting load ? I've necked down and fire formed 30-30 to 7-30 waters and found the stouter the load, the better it seemed to work for me but that may have been pure luck and at that time I did not know about crush fit or jamming to the lands. Good luck and post your results. I am watching this as I just ordered a .223AI barrel and most likely will need all the info I can get. Lol.
