Well, I have and SKS and I had an AK, and ran nothing but wolf through them both, never had any problems. I also shot quite a bit of it through my Makarov, no prblems there, either.
I put some through my Bushmaster, and it didn't take too kindly too it. It ran, and cycled all of it, but after about 200 rounds, it began to run kinda sluggish. It didn't perform all that well downrange, either. When I cleaned it, it was getting green crap out of my chamber (I know the new wolf stuff doesn't have the laquer anymore).
I would probly give Wolf a shot in my M1A. I would buy a couple boxes and see what happens, but my expectations wouldn't be all that high.
FWIW, when I was stationed in CA, one of the local indoor ranges barred the use of Wolf ammo. Their reason was that customers were renting range guns, and putting the Wolf ammo in them, and they had a couple of KBs. Knee jerk reaction, perhaps, but there it is.
