Most "old" ammo 10-20 years is gonna fire just fine. Just check your casings and primers. Also if it's older ammo your primers might be corrosive.
Keep in mind that SOME old ammo is quite valuable. Check with SPB directly.
Best to give point blank a call. Some old ammunition & especially the box are collectable. Please keep in mind, just because it's old does not mean it can't still be discharged.
