NOT a bad price these days. Most of this stuff ended up in little wars in Africa. We got just the tail-end of what was in storage from before the 1957 changeover.
If you fire it and the necks don't split, save the brass. It takes a small .177" Berdan primer now but a RING CRIMP can tighten the primer pockets to .175" for a Small Rifle primer. Then you drill out the Anvil and reload. Anneal the mouths before loading: saves on future splitting.
Alternatively, the base can be reamed to handle a .210" Large Rifle primer. there is enough meat there; it is the same base size as Carcano ammo.
Brass also can be formed from Carcano or from MS, although that is a nasty-expensive way of doing things.
