This 9mm case wall thickness, capacity and taper question has been worked to death but I can't seem to find posts explicitly saying which cases to look for when sorting range brass.
Inside taper is bad news with cast bullets and some brands of cases have severe taper.
If I was going through a pile of brass what cases to look for and while we're at it what length?I
Thank you

(Taper can cause a bullet to be resized.smaller)
