Factory Steel Cased Winchester 9mm 115gn Split Case this past weekend. Shooting a NR Berretta CX4 Storm 9mm rifle and spent case failed to eject but bullet fired normally sounding and hit steel gong. Used cleaning rod to push out and found almost the whole side of the case split open but not quite to the end. Checked and cleaned chamber and barrel nothing fouled so not sure what happened shot the rest of the box of 150 rounds off with no more issues. Anybody have similar issue with this ammo or any other brand?
