thank you for the feedback. I a full resize primer die that I bought. I even invested in a .223 case gauge. I checked everything brass I did and I even bought a "go no gauge" as well. Everything look normal didn't see anything wrong. I must of missed something with the 223 case gauge.
I started watching videos on next resizing and seems simple to do. From my understanding but if I'm wrong please correct me.
Get brass that you only shot once from your AR. I bought Hornady Lock-N-Load Headspace Gauge 5 when I first started.
Then measure the fire case and zero it out.
Then de-prim and resize .
Measure the case and having it between 0.0020 to 0.0030 correct?
I was watching this video on how to adjust the die would this work for an AR?
Please let me know if I'm over thinking this or not.
Thank you once again for the help.
