Although it might devalue the full box from a collector point of view, I would be opening to check the condition of the ammo. I had a few unopened boxes of Kynoch 404J (yellow & red boxes) and when I opened them the cartridges all showed early stages of corrosion. They cleaned up fine and had no pitting so I got them in time and they shoot fine. These ones were the later loading with nitro powder so gives you an idea of how old (or young)they were.
