Both of you make good points re: the brass catcher...
My main reason for including it was cleanliness...once I get this bad boy up & firing, it's gonna be bad enough what with Fargo & surrounding areas bieng knee deep in zombie carnage.
I figured, it would be that much worser stubbing your toe or cutting your foot (& risking certain zombification through an open wound) on brass strewn willy-nilly about the post apocalyptic landscape.

I'll let ya know how it works out.
