Got an old box of Remington 30-30 Core-Lokt, but that's not important. What might be is the Pay-less price tag of $3.63. The shells are old with light tarnish, but look good. Any reason they can't be fired?

Even ammo from the First World War is useable, as long as it's not too corroded. Usually visible corrosion (often a bluish-white crud around the neck of the casing or around the primer) means it's been exposed to moisture and it's no good. Just remember that old ammo us usually corrosive, since corrosive propellant lasts longer, you need to clean your gun the second you're done firing it.

Just toss anything rusty and make sure you clean it well afterward.

I've used plenty of WW1 and WW2 era production ammo without issues. Irie is correct.

its jonas, about 1......

old shells are all i shoot...

are they making new ones.. ?

As long as they aren't rusted or beat up you're good....
