bought some old .303 ammo...any good?

I was mainly interested in finding out if this is "collectable" ammo that shouldn't be fired, and if the slotted charging clips had any collector value. And the age of the milsurp ammo kinda concerned me too, as to whether it's safe to shoot or not.

The slotted charger clips do tend to fetch decent money on e-bay. Push the WWI angle and watch how much they go for. I was pleasantly surprised when I put mine on.
