Brass vs steel cased ammo

There are two major types of centerfire rifle cartridges available on the market today:
  • Those which are loaded with steel, and
  • Those which are loaded with brass
This seemingly simple variation has caused a never ending stream of argument, discussion, speculation, and questioning from new and seasoned shooters alike.  Complicating the conversation are other variables that typically get lumped into the argument without proper segmentation, such as:
  • The different coating options available on the steel-cased ammo (lacquer or polymer)
  • The different projectile loadings available (copper jacketed lead, the bi-metal coating that most Russian manufacturers use, etc)
  • The different propellant (gunpowder) burn rates
Our team decided to try something ambitious and daunting:  to provide the best resource and data available to answer these questions once and for all through objective experimentation and observation.
We realize this is a lofty and borderline arrogant goal.  We’ve done our best.  Please keep reading to see if you agree.

If you are using an Ak-47 , you need to use the steel case ammo. The sloppy tolerances built into them will cause brass case ammo to expand in the chamber , causing extraction / jamming problem`s. Also this is off topic but , it is a MUST that you get spare part`s for whatever weapon you choose to use. Any thing that`s going to break or wear out under long use , spring`s , extractor claw`s , gas piston`s etc. Molon Labe / Fuck Obama.
