so much bad info in this thread....
Hornadys cases are lacquer coated (Bought from Barnaul, (Brown bear Cases)
They are for people who want to train with quality ammo, but save some money.
They have very good bullets and power, so they are accurate, they just save money on the case/primer
Its not cheap plinking ammo, people buy it instead of the $1.50+/rd ammo they would usually shoot.
And yes, the lacquer causing the cases to stick is Myth, its because steel doesnt expand and contract like brass, so the chamber gets fouled and causes cases to stick if not cleaned well.
Silver Bear is still steel and can get stuck, but the zinc is smoother so its supposed to help with extraction. (saving are usually minimal between cheap brass ammo though)
Steel ammo will not snap and extractor unless its made of plastic. People shoot thousands of rounds of this stuff in AR's everyday and I have yet to hear of a snapped extractor
Older Wolf and Tula are from the Tula plant (worst Russian ammo quality in mosts opinions)
WPA Military Classic and all the Bears are from Barnaul (much better quality)
All russian ammo has a "Bi-Metal" jacket, meaning its a lead core with a copper plated or copper washed mild steel jacket
Yes its Dirty
Yes its Inaccurate
Yes its Underpowered
Yes it has a Bi-Metal jacket
Some AR's will choke on it no matter what, but the vast majority of the time it will run fine if its run in a quality gun that is set up correctly, and the chamber is cleaned occasionally.
It also helps to no shoot Tula, as many more problems are reported with it.
Here is an excellent link to all the info you need about Russian ammo. Some info may be a bit outdated
