About 22 years ago when I started reloading bottle neck .223 rounds, I did the same thing that you have done. Did I shoot those rounds "NO". I demilled all of them and scraped the brass. But I only had about 100 of them. The choice is yours. I would imagine a lot of FTE's, maybe FTF's.

The difference between max length and min length on dillon case gauge seems to measure .008". When a spent case is inserted in the gauge it is about .001" proud of max. My resizing was taking a case from .001 over max to .001-.002" under min. I measured all factory rounds on hand. Of the 5 types I tried most were in the middle and one was on the minimum (Hornady steel match).
These measurements were taken using the depth gauge on my calipers(the slide portion that protrudes from the end)and the Dillon case gauge as a reference.
I've read the ABC's and understand the concepts and risks. Are there any experienced reloader's out there that feel strongly one way or another about the safety, life span, etc of this brass? I ask since I find it hard to believe I'm the only newbie to follow the directions on the box and push the shoulder back too far.
