Lapua .223 brass

[SamsonMan22]

Just when I was thinking the starline was great brass I saw the posts about the case separation. Nearly all of mine have the ring around them but we’re holding up fine until today. This case was on its first firing, I sectioned some of my other ones to see what they looked like inside and all the ones I did were fine so I guess from here on out it’s a gamble on whether or not they hold together. I have a mixture of 5.56 and 223 all were purchased from late 2023 until late 2024

That’s a really strange place for a case to separate.
