Valcartier Industries M80 Ball ?

[mcm308]

I didn't know where to post this one..Does anyone know anything about this ammo ? I have 7 boxes and don't know what to do with it. All the boxes are sealed and I don't want to open any of them till I find out about it. I never heard of it before and there's not much info on it. Is it worthy enough to go through an M40A1? I was told it was collectors ammo. Thanks
