"large quantity... (.22) "
The problem is shipping and handling, even for the big outfits.
Might try Mil Surp wholesalers, that you can get to in person.
There was a couple dealers in this region that drove to wherever the transprting ships are, loaded a 1-ton pickup and a large box trailer at the importer's place, then drove back here.
That's a LONG drive, but their retail price was great.
If you find someone who deals with Russian ammo (ie Wolf) in full cases (instead of single boxes), they may have some steel case .22 at a good price by the case. Smelly, or strange smelling, but I was impressed with it. Russian "Junior" target ammo was great (cheap, accurate, etc), and I was getting it for $5.50 a brick not all that many years ago.
If the local retail is $2 a box, the seller has no reason to sell it below $1.75 anyway.
