I just saw a new box of .223 rem. cartridges that by all appearances were made by Ulyanovsk, but the box says they were made by Tula. The Ulyanovsk logo is on the box front and sides and on the headstamp, but on the back of the box it says made at Tula. Did these two manufacturers merge?
Very similar new box of 7.62x39mm has the same design and headstamp layout as the .223, but says made by Ulyanovsk.
Maybe Ulyanovsk is making the cases and packaging and then sending them to tula to load?
