WK Owners (steel case ammo)
- Thread starter Double Denim
- Start date
Used Barnaul, MFS (Not always the same as Barnaul), Norinco, TulAmmo, Wolf, and some surplus. 223, 5.56, 7.62x39, 7.62x51, 308 and 30-06.
TulAmmo and some China Surplus in 308 are the only ones I ever had issue with, split cases, over powered. Some batches are better than others. I had a batch of MFS .308 SP 140gr that pulled under MOA at 80m, while the new batch of the same thing from Barnaul was closer to 2", IIRC.
I use the .223 for groundhogs and range time often, MVP, AR, Benelli. No more issues that I find with cheap brass or surplus.
I've put 3000 through T97's with no issue. His WK and one of my AR's can't use it.
Glad this topic came up. I was researching this and found this post on Lucky Gunner: https://www.luckygunner.com/labs/brass-vs-steel-cased-ammo/ I wanted to order steel case (or bi metal) but this has me second guessing my choice.

I think most people bash steel cased ammo on the base that they gunk up the chamber, which haven't proven true.
It may make the case stick tho upon extraction, and is more likely to separate/break than brass that would deform under similar conditions.
But again, barnaul, mfs and norc copper washed stuff have been nothing but good in my firearms.
Glad you were lucky with your tula Shawn, I definitely was not and after the incidents, found quite a few stories resembling mine and never again.

Is the 5.56 surplus lacquered steel?
Ive only had issues with lacquered steel x39. might have been Czech surplus? Grey coloured case, comes on strippers and in a robin egg blue box. I’m sure everyone knows the stuff. However copper washed Chinese surplus hasn’t been an issue. Heat and lacquer might be the problem.

Haven't seen any surplus with lacquered cases, just Barnaul, which has never been an issue. Although made in the same place the MFS I have bought always seems to be Zinc.

""BARNAUL have developed external coatings for the steel cases which actively reduce contact wear in the chamber – the Hunter Grade, for example is marketed with Zinc, Lacquer or a new Polymer coating on the steel casing – are you seriously going to say that these coatings are harder wearing than steel? These exterior coatings are carefully administered through guarded procedures and include applied metals as well as scientifically formulated specialist lacquer coatings. The especially applied external coating of the steel cases, together with the reduced pressures and lower operating temperatures, greatly reduce barrel and chamber wear and assist in accuracy.
The projectile too has had some major attention. The jacket is a specially developed low-carbon steel, which is coated with copper and passed through a double heat treatment during the manufacturing process. This allows BARNAUL to temper and finish the product so that it looks and behaves like copper.""
