Yes, redding 223 type s FL bushing dieThe flare can happen when you step down too much at once. My process is:
step 1, size in a 223 die and set my shoulder and the neck comes out at .243" with the expander removed
step 2, size in a Redding Comp bushing neck sizing die with a .235" bushing
step 3, size in a CH4D die that has the neck diameter I need for the brass I am sizing. I have 3 different FL 20P dies in total with different neck diameters for the brass I am using
But you can do the steps I do with a 223 bushing die with nearly the same results. Your shoulders (case head to datum) are all over the place. Are you using a neck sizing or FL sizing bushing die? You need to use a FL bushing die.
