Wow, good on you. They will work in Model 100 auto and Model 88 levers ONLY. OBTW.... worth a good chunk of change. 75 dollars or so. Probably work on 308 but I don't know that for fact.
Let me know where you want it shipped too. Glad someone could use it. I would probably just wind up looking for a rifle that's missing the mag and trying to justify another guilt buy.
