Anybody here familiar with "Saga" shotshells?

They appear to be made in Spain. And are really economical (aka cheap).

I just found too many loads to list for sale at a shop here. The 12 ga. in #6 steel (which I'll use for gray partridge, quail and grouse) were only $6.50 a box (25). And the 20 ga. stuffed with #3 steel (a decent pheasant or duck load) was the same price. They were 70mm length, 28gm and 24 gm. loads respectively, at 1350 FPS.
