Does it look like this?
If it does, take note of the relationship of the breechface with the case extractor groove. This is called a Bolt Over Base misfeed. It's common with a weak magazine spring or too much recoil spring...or sometimes both. Essentially, the slide is outrunning the magazine, and the breechface catches the case in the extractor groove instead of the back of the rim. Butt goes down...nose goes up...and there ya are.
