Years ago Lucky Gunner did a test of steel vs. brass 223 ammo and while the steel case myths were busted, the bi-metal bullets being hard on barrels was confirmed. They had this chart that showed rounds vs. accuracy:

When my povery pony was new I recorded a handful of 5-shot 100 yard groups with 55gr wolf, and the average was 2.1".

At 4712 total rounds of wolf/tula bi-metal stuff, I put the 1-8x back on along with a rifle stocked lower (has a better trigger and easier to shoot off the bench with a rear bag vs. the magpul 6-position I normally run) and fired a few 5-shot groups of the same wolf 55gr from before.

Those 5-shot groups averaged... 1.97".

So either it's gotten better as a rifle, I've gotten better as a shooter, or properly aged wolf 55gr is more accurate than fresh. Probably not that last one.

Even if I wasn't getting all the accuracy out of it when it was new, it's still doing fine now. Time to shoot it more and verify again in another 2500-ish when it's eaten another set of gas rings.

Call me a snob but only the best Russian rounds go through my barrels! šŸ˜‚

haven't you heard? the propaganda specialists say you're supposed to pour out your russian vodka to show support for the war. send me that evil russian ammo and I'll make sure it gets shot up real quick like, in the name of science. you trust the science, right?

I poured my vodka out already and to show support I will shoot all my Russian ammo into the dirt. unless they give me better targets...
 
The first thing to touch the barrel of my new DD upper was some lacquered Barnaul. Steel will be a rich guy flex pretty soon.

Thanks for the info, @Jayne !

Bi-metal bullets can be hard on steel targets. We are likely going to prohibit them at our 3-Gun matches at VOD.

Watching them impact on steel during the last couple night shoots was very informative. The sparks that fly off the steel was impressive.

Doubt you'll have much trouble with it pretty soon.

They make (made?) steel case with regular bullets, labeled "range safe". I doubt we'll see much more of that stuff for a while given it's source.

I've got a few boxes, always meant to accuracy test it. Now it's moot.
 
Is that chart x axis x100 or x1000? Short of x1k, I'd have trouble accepting that.

The way i see it a 1000 rounds of ammo is more than the cost of a quality barrel.

I have absolutely no qualms about shooting bi metal or steel case oit of all but a few guns I value as collection pieces.
 
Been a while since I read it but werenā€™t they doing a lot of high-temp mag dumps? Your barrel will last way longer with routine shooting than with deliberate mag dumps sponsored by an online ammo warehouse
 
I've sent about 400 rounds Wolf Performance through my F1 AR. Only one jam when I tried a ā€ Solvent Trapā€.

Also shot a couple boxes of Winchester Green Tips for fun but like the cheep steel rounds.

My steel targets only complain about the Green Tips at 50 yards or so. The targets tell Wolf to keep huffing & puffing.
