Yours are Russian of current manufacture. I don’t know if they are imported as much as they used to be, but I don’t see them nearly as much at gun shows as formerly. I chronographed several brands a few years back, and out of a rifle, I was surprised to find the MVs are quite low - barely 1000 f/s. That’s really subsonic. Also, from a pistol, the MV was determined to be only a little less than that.
I have one bolt-action rifle that has always given extraction problems using conventional brass-cased .22 rounds. The Russian ammo extracts perfectly, so I restrict that rifle to shooting only the Russian steel-cased product.
If you want to know more about your steel .45 ammunition, there are many postings here about it, and I think one even provides a website link to read “Bullets by the Billion,” which is a book describing the history of the WWII Evansville plant that made them.
