Ditto-
Some of the fired DT cases were leaving a visable smiley on the case & you could feel the nickle had cracked w/ your finger nail. I don't care to push the edge that close. I have had real good luck with Hornady ammo though. The fired Hornady cases & my re-loads don't leave a bluge. Everyone has their own opinion but the XTP bullet is hard to beat. These are some numbers fired through my stock G20.
