Really like BLUE RIDGE BRASS!! I get all my 40 cal (filthy considering that I provide the assets and can easily clean it myself) cases from Blue Ridge Brass! I get it from the 4,000 at a time and haven't experienced a 10mm case from the bunch, nor a 9mm https://oncefired40calbrass07417.smblogsites.com/38454012/fascination-about-40-cal-brass
