I will say though that I was surprised the rifle shot that well...after all it is an AK, lol.
AK's are not nearly as inaccurate as typical Internet lore makes them out to be. As has been pointed out elsewhere, the single greatest factor resulting in AK inaccuracy is operator error/carelessness, not the mechanical limitations of the platform.
Hard primers, corrosion problems, powder is dirty as all get out, many of the rounds have STEEL projectiles with copper plating or copper wash on the outside
Berdan primed so the cases aren't easily re-loadable...
The primers are supposed to be hard, at least in 7.62x39mm and 5.45x39mm. Using soft U.S.-market civilian primers in an SKS or AK is unwise from a safety standpoint, as those primers are out-of-spec with regard to the platform and will increase the risk of slamfires. I have never heard of an AK slamfire resulting from soft primers, but I have heard of several in the SKS.
Steel cases are not reloadable, so whether they are Berdan or Boxer primed is not really an issue. The primary market for Wolf is for people like me who don't reload, I suspect; there are plenty of more expensive alternatives out there with reloadable brass.
I have never seen any corrosive Wolf, and rumors to the contrary are many years old. I kept few fired Wolf steel cases in humid Florida just to see if the insides would rust (which they would if corrosive priming were used), and they never did.
Importation of steel-core 7.62x39mm was banned in 1994. It is still legal for calibers larger than .308, but I've never seen any. Many Wolf calibers use a bimetal jacket, but the alloy is quite soft and does not cause excess barrel wear, unless one is in the habit of bumpfiring and posting videos on Youtube.
