FWIW, the only FTE's I had on my BHP were with Wolf ammo.
And I broke an extractor, which I believe was caused by the Wolf ammo.
I had some get so stuck that I had to manually open the extractor, field strip and beat on a hammer with a dowel down the barrel in order to get them out.
Yes, I believe they are "fat" (wider than spec.) And I believe that the "lacquer melting/cooling syndrome" can muck up your gun.
So I no longer use it in 9mm.
My AK, on the other hand, loves the stuff in .223
