I had a nice quiet morning at the range. On going to police up my brass I found a steel case that had cracked down the middle of the case body. What could have caused that? The other 49 steel cases looked fine and zero of my brass cases (about 60) seemed to have any pressure signs or other issues. They all looked like healthy once fired brass.
I didn’t inspect EVERYONE, but I looked over at least 25 or so of the steel cases I could find and 30 or so brass.
Flaw in the steel case? Too quick of an extraction (I’d assume that would be case head separation). Chamber issue?
Not sure which upper it was shot out of. I was shooting my “old” 20” .223 wylde upper that had maybe 1000 rounds through it with no troubles and also my newly rebarreled 16” .223 wylde upper. But I only shot 10 of the steel cases through the 16” and 40 through the 20”. Almost all of the brass was through the 16” (just 10 of the brass through the 20”).
If it helps it was Hornady 75gr steel match.
