Actually, I was talking about the cases of military surplus. Right now they have a crate of 1100 on for $449 ($100 off).
What Cabela's puts on sale is very modern Norinco 7.62x39mm ammo produced in 2019, 2020 and 2021. So-called "red box ammo" (it used to be a "white box"). It is 100% non-corrosive and has nothing to do with "surplus". The price in Cabela's comes to 56 cents/round which is not as cheap as it used to be but still reasonable. The "red box" rounds are 100% reliable in an SKS or a bolt-action, long gun chambered for a 7.62x39mm round like, for instance, my Ruger American Ranch. It is not very accurate ammo, rather passable accuracy. I miss very much Barnaul ammo which I liked very much. Much more accurate than a "red box" one. Damn sanctions on Russia!
I've already bought about 3,000 of these Norinco "red box" rounds from Cabela's. So, as long as Norinco can sell reasonable quantities of this ammo in Canada I don't expect any "drying up". A number of other firearm dealers also sells the same Norinco ammo in this country. I'm sure that there will be still demand for Norinco ammo in Canada into the foreseeable future.
