i ended up modifying the die and chamber.
with the new die the steps for making brass now is just
-cut to 24mm
-run the brass full depth in "side 2" of the die
-trim to 22.1mm and chamfer.
i no longer need to neck ream or turn the brass, the new chamber fits the .223 bullet and 0.020" x2 neck thickness
and to resize the fired brass i can just run them thought the same die
i have 5 rounds with primers in them i plan to fireform the cases, (they are the older style with smaller necks, made before i changed the die and chamber)
i plan on using jacketed bullets for the 22 hornet (40gr)
I have a loaded dummy round, its the revised style (so as they all will be from now on), 40gr flat base jacketed soft point. passes the "plunk test"
over all length is 30.5mm / 1.200"
brass length is 22.1mm / 0.870"
(i could use a crimping die, to soften the edges of the mouth but its a single shot break action so it would feed fine)
the shoulder is a bit sharp still but it chambers so i want to compared it to a fired formed brass to see how it looks once the die is being used to resize opposed to forming the brass
I'm not sure what i going to call this little round yet but the metric name for it would be 5.7x22mmR
I'm disappointed the name "two twenty rook" is used already
