Mosin nagant 7.62x54r czech silver tip ammo 680 rounds sealed tin box

I have an unopened sealed tin box containing 680 rounds of mosin nagant 7.62x54r czech silver-tip ammo. This is 1964/65 produced corrosive primer, ammunition. The czech silver-tip is no longer being imported (my understanding) & is getting harder to find in original sealed boxes. The ammo has a great reputation for it's accuracy. Again,this is an original sealed unopened tin box & that is how you will receive it. $450.00
