Built .223's stuck in chamber

I recently assembled my dillon 550 and spent a good part of the day learning this machine and adjusting all these dies. This is my first time making any batch of ammunition at all. I don't believe i have one of my dies set properly.
I have #1 FL sizing die #2 powder die #3 bullet seating #4 crimping

I made 7 rounds of .223 initially and hand cycled them through my Bushmaster and 4 cycled by hand with no issues, 3 stuck and took excessive force to cycle out of the rifle.

I took a marksalot to the 3 that cycled badly and found that there is a 1/2in area where they are making friction, on the bottom 1/3rd of the brass casing. I took a picture but I am not sure how to post pictures to the forum.

Additionally, i have noticed that my CCI primers are being marked slightly as I hand cycle (without firing) the rounds.

Any help would be appreciated! Thanks

The most likely cause is that the size die is not quite down far enough. We strongly recommend using a headspace case gage to aid in adjusting the size die down to minimum headspace. We have a video available on our website under resources to show use.

Thanks! That worked very well. It simply wasn't down far enough.
