Recently I picked up a box of 9mmP by Steel Tiger Ammunition, Allison IA. This was advertised as “New Ammo” made in the USA and loaded with a Sierra JHP bullet. When I received the box, I was surprised to see that the cases were made by Sumbro in Macedonia. Clearly the bullets are US made. In the photos below I show both the Sumbro loads made in Macedonia and the Steel Ridge loads. The most obvious difference is the bullets (note the Sumbro bullets are brass jacket while the Sierra are GM), and the primers with Sumbro having brass primers and Steel Ridge being nickel. It seems pretty clear that the Steel ridge ammo was loaded in the US with cases apparently bought from Sumbro.
No end to this kind of stuff in our new global market!
