it was found that the cases tend to stick into the magazin when loading the first round into the chamber. reason is the semi rimmed design give the rim of the upper cartridge the chance to hang into the extractor groove of the lower cartridge. this happen only when loading the first round the next rounds come flawless from the magazine because of the great force while auto loading. so the brass see the lathe again and I change the extractor goove like original ammo giving it a taper so the next case cant hang there anymore.

right old groove - left improoved design
