Steel Ammuntion? In my AR?

[JasonB1]

See a lot shot in matches without issues.

Has anyone done a test on this or is this a myth? I'm curious on how a bi-metal jacket is going to prematurely wear a chrome lined barrel which is a very tough material.

As a matter of fact, yes.

Russian or US ammo?

Mostly Wolf with a little bit of Brown Bear and Silver Bear mixed.

I am thinking the steel cased ammo is going to be harder on the bolt.

There will be more bolt thrust with steel cases than brass when loaded to the same pressure. But steel cases are generally loaded to lower pressures to keep the case from sticking in the chamber

I came across this video that supports the side that steel cased ammo isn't going to damage your firearm. I'd want to see more data to know for sure but I thought this was very interesting none the less.

Didn't watch the whole thing, but there's a balance. Hardness is also 1 test. There are many different tests for steel That must be done to ensure function. Ys, %elongation plastic deformation point, etc.

Good reading.... Russian steel of varied sorts is 90% of my 556 shooting...one carbine is well over 10k with no issues... Gets cleaned every 2500 or so. I'm thankful for it😀

No go in 223 rem or Wylde. Might work in 5.56 chamber

Two of my training carbines have .223 Wylde chambers. I've fired tens of thousands of rounds of steel case ammunition through them without issue, one thousand rounds in the past two weeks.

Neither carbine has a chrome lined barrel. Barrels and bolts are replaced at roughly 12,000 round intervals, sometimes 10,000, sometimes 14,000. Both carbines are treated like stolen cars. Except for replacing gas rings every once in a while, not much gets replaced between new barrels.
