Trojan Barrel has wobble when open.

I have a VH 16g that is loose as a goose when open but tight when closed. Birds still die and it's been like that for the 7 years I've used it. Someone looked at it at Hausmann's (Brian or Dan May???) and said "Shoot the damn thing it's over 100 years old you'll be dead before it's a problem." I think that was solid advice for me anyways.

Joseph: I realize I'm talking about an inferior product but a beer can shim has worked great on my 1906 L.C. Smith, and is easily replaceable.

I guess this guarantee was marketing hyperbole
