The bullets on the Russian made ammo are made out of steel. They are copper coated. That is where the wear is coming from. I’m glad that someone finally did a test and proved that the Russsian stuff is JUNK!

Curse me if I’m barking up the wrong tree, but as far as I can remember barrel – throat and gas port – erosion has nothing to do with the case material. It’s a combination of the propellant gas temperature, gas species produced, gas pressure and the material properties of the bullet and barrel: for example the frictional, melting point, elemental composition and hardness characteristics.

The case material will be the major factor on the wear of the chamber and extractor, other than the materials these two components are made from. The case and its coating, if present, will also affecting the extraction and feeding process.

Thats my change barrel point, out .100 unless it losses X count at 600 earlier as a Wilson or DPMS might. Have definitely had the longest barrel life with krieger`s.

Interesting Barrel Wear and Throat Erosion figures. out .050 with a 55 grain bullet sounds about right for 5000 rounds. I shoot 77`s and 80`s or 80.5`s and the throat goes out .100 between 5000 and 6000 rounds. About 1/4 of these rounds were shot rapid fire HP Comp. This has been the case with several SS barrels of various manufacture.
