The SA-22 will drop empty cases down your shirt sleeve if you're not careful. That can be uncomfortable, so I'd go with the levergun.

I've got an old Remington M24 (same basic design as the Browning) and it never fails to drop at least one down my sleeve every time I monkey with it. I like it a lot, but I like NOT getting burned by a fired case better.

You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
