Mfs is even worse in my book, bimetallic projectile...
Bi = 2
Metallic = composed of metal
Yes, those projectiles are composed of 2 metals: copper & lead
Because it's dirty garbage and typically doesn't produce decent groups and just adds to the bad accuracy of the Tavor and many other rifles. If all you want is to go out and make noise it's fine though.

I wouldn't agree with that.... Every shot of Norinco has been very clean out of my gun. I shot over 300 rnds on the first day trying the stuff out. Looking down the barrel after. I wouldn't have thought the gun had been fired, if it wasn't me that had just shot it all day.
Typical, as far as I am concerned. I really don't clean my shooters...I clean them once a month whether they need it or not and pretty much as a formality only. I have never seen barrel fouling in my chrome lined barrels and my piston guns have always been squeaky clean for the most part. My AR15, on the other hand...? After a month of shooting I would get carbon build up on the damn bolt components that nothing short of a wire brush and road rage would take off.
With any semi auto one of the important tasks I do at some point is run it until it starts to jam and count the rounds. It isn't exact but it is a good indicator of what your cleaning intervals should be. I haven't done this yet with my Tavor but my HK45 USP pistol will start to jam after 500 rounds - and I think that is because I burn W231 in it and that is one filthy mother&*^$# dirty powder to work with. I need to do something about that too one of these days...

Pretty sure mfs has a steel core inside and is copper coated. For us with neutered mags it would take atleast 10 000 rds to notice accuracy lossBi = 2

Sorry, incorrect.
Bi-metal jacketing is a copper-steel alloy for bullet jacketing itself, Bi-metal jacketed bullets will cut your barrel life down to approx 1/3 to 1/4 of it's expected life.
Not all cheap ammo is bi-metal and don't be confused with metal cased ammo, this is the bullet itself that ruins the barrel.
There is a really good article in one of the Norinco ammo b!tch threads from a while back that I linked to which explains it really well.
So it's steel jacketed, with copper only thick enough to make it the color of copper.I took a sampling of bullets from different manufacturers (Wolf, Herter's, Brown Bear, Norinco), sectioned them (cut in half), and polished them. I took the polished cross-section samples and put them in a Scanning Electron Microscope (SEM) and performed Energy Dispersive X-Ray Analysis (EDX) on them. What in Fraggle Rock does that mean? To put it briefly, EDX tells you what elements are present in your sample. I was then able to take that information and make a map of where each element is located on the sample. This enabled me to divine the answers to many of my bimetal related questions, the reality of which will shock you!
OK, it's really not that shocking. The bullets turned out to be lead-cored, but steel jacketed, with a very thin copper coating over the steel. So, the term bimetal refers only to the jacket and not the bullet as a whole. How thin is this copper coating, you ask? Very thin. I measured five different bimetal rounds and the outer copper coating was only about 20-30 micrometers (abbreviated µm). How small is that? Well, there are 1,000µm in a millimeter and the hairs on your head range from around 50-100µm thick.

Ok what .223 projectiles are bimetal that we have access to? I know norinco isnt
Im sorry but i read enough threads about the norinco ammo that i will never fire that in my 3000 dollar rifle, that would be profoundly stupid of me!
I thumb through news papers every day and I can tell you that I don't believe everything I read. You should try things first hand before making a potential miss guided conclusion on something. I could tell you about how this ammo runs in a few of my high end guns but you should find it out for yourself. I'm happy with it.
How dose Norinco ammo wear out a barrel faster then a US brand? I still don't see how this can happen? The copper jacket over lead is still a copper jacket over lead... There isn't anything other then copper in the jackets, I know this because i have tested it to prove it to myself.
