Shane, its funny but I bought an A J Aubrey with 32" steel barrels last summer. My son found it in a local auction out in Bozeman, MT. Mine was just a little off face also, and the rear trigger is a bear to pull. I shot ducks with it last Fall but I shimmed the hook with a layer of Scotch Tape which tightened it up enough to lose the rattle. Those long barrels just keep swinging when I shoot at a passing duck so I shoot it surprisingly well.
If yours rattles when you shake it, it is off face and will get worse unless you do something to tighten it back up. Tape's cheaper than gun-smithing, but certainly not a permanent fix. I'm undecided whether to spend the money fixing the trigger pull and rejointing, but I do like the gun. Low pressure 6s will most certainly take down a turkey unless you insist on 40+ yard shots...Geo
