Wolf is steel jacketed and can attact a magnet. Indoor ranges just freak out because steel core ammo can damage the traps. Its just easier for them to ban any ammo that has steel in the bullets even though steel jackets usually aren't more damaging than copper jackets.
True steel core ammo is like the 5.45x39 stuff that is currently in the country (you can import rifle ammo that is steel core but not pistol ammo).
The last steel core AK ammo was the chinese stuff that was last imported in the early 90s.
But in reality, nothing should get MORE damaged by steel jacketed ammo like Wolf than just plain copper jackets.
WTF are you talking about?
I'm pretty sure the OP was questioning the STEEL CASE, not the projectile.
While there have been actual steel jacketed bullets, they are plated in copper. How many rounds would you get out of a barrel shooting steel on steel? Wolf ammo is a steel case and some variation of a FMJ COPPER JACKETED round. Different weights and some may be hollow points. And steel CORE ammo is still available if you want to pay the price. For 5.56mm look for "SS109" I bought some Olympic stuff a few years ago and they make nice holes in things. You are right about the ranges not wanting the steel core stuff, the traps take a beating.
Steel cases are supposedly rougher on the extractor, (which has been mentioned,) and more importantly on the chamber. That polymer coating has a few uses. I'm sure it's used as a rust inhibitor, but it is also meant to seal the primer and bullet ends for waterproofing, and it lets the case slide into the chamber easier. The problem with the coating seems to be after firing a lot of rounds, there seems to be red dust all over the breech. Some claim this will eventually lead to jams. I've put a couple hundred rounds through my mini-14 without a problem. Should be OK for a single shot.
Oh, here's a good page:
