Now I don't know for sure because it's been awhile since I shot it . I remember the bullet looking different then my other copper jacket bullets . More yellow then copper . That led me to believe they were brass jacketed bullets . . That tells me I shot at least 300rds of it . The other thing that stands out is that nothing stood out about the ammo . That to me means it likely was good , not great or bad and all must of went bang . I still have 3 of the round containers I use to hold other stuff
As for reloading
I just so happen to have prepped and sized a couple hundred of those cases in the last couple days . There were 3 things that stood out and none are an issue really , just something I noticed .
1) They almost all ( 95% ) measured on the longer side of the 9mm specs .752 to .754 . Because of this I trimmed them all to .750 .
2) When chamfering I felt the cases were a little harder material then other brass I trimmed .
3) The rim on a few ( not many 8 to 10 of 200+ ) were either pretty fat .055 or very thin .035 . I set the thin ones aside thinking those rims may rip or brake on extraction . I have not loaded any of them yet
