Howdy Pard,
A lot depends on the enviroment that ya store them shooters in. I store my gunz in a gun safe with a "golden Rod" dehumidifier, but there ain't room in there fer alla my irons so sum of them are racked in the gun room. However my basement is a controled enviroment...it's heated & airconditioned...so it's not damp or anything like that. I take no special precautions when I put them away fer a spell. I do however check my guns every few weeks just to be on the safe side. Have found some surface rusting on a smokepole once, that I didn't clean good enuff, but no other problems ever cropped up during long term storeage.
So I'd say that the extra squirt of lube, along with an occassional check to make sure, should get ya by fine. But if yer storing them in a damper place I'd make a routine of checking them regularly and oiling them again when checked.
