Besides it being corrosive and requires you to properly clean rifle after shooting, there is now a dynamic no one ever seems to mention. That being this stuff is surplus ammo for a reason, its self life for military (whichever whenever) was over and was sold off. Now, many of us bought it in the last decade and mostly, it fired and was serviceable but now in 2020, most Spam Can ammo is 40 yrs and older. Its deteriorating with age, wasn't meant to last forever so if you are sitting a stash, better think about shooting it or ending up with CLICK BANG...to CLICK CLICK ammo. Of course you can salvage the bullets for reloading purposes if the ammo goes bad.
Shoot it but if you are hoarding ammo, spam can ammo is not an item that has a long life left in it.
