Sig Ammo Case Change

I’ve been using Sig Elite V-Crown ammo as my carry ammo (cheap enough I can afford to dump a few mags of it when I go to the range).The stuff I’ve been getting has been the small blocks, and the case has had a steel-colour (as pictured on the Sig website). Last week I bought a brick of 50 rounds and the casings were a standard brass. The primers are also different colours.The markings on the casings, and the shape of the actual bullet seem identical.Did Sig change something recently? Or did I get a different “line” of Sig Elite (non “V-Crown”? But the hollowpoints are shaped the same?)? via /r/CCW http://ift.tt/2yAn9Db
