I did 300 cases, they were .050" short, but grew within 2 sizings. They will need to be squared up after sizing, all of mine came out longer on one side on the neck, even using powdered graphite INSIDE the necks didn't eliminate this. They will be fine to use as is.
Have not tried 223 brass! But size 204 ruger brass into 17 rem. Push shoulder back first with 222 die then use 17 die and neck turn! The hornady brass dose not split necks like the rem stuff!
