Just shot some Wolf 9mm. No problems.
I don't have anything in 5.56 so I can't comment on that. I did just run a hundred rounds of Wolf 9mm through two pistols. No issues. In fact I had two FTE on the Taurus 99 and one on the Taurus 111 with some older Winchester ammo.
The only issue I had with the Wolf was a failure of the slide to lock open after last round. Only happened once. Normal cleaning. No observed unusual residue in either pistol. Am planning on using it for practice and continuing with Silvertips for defensive needs. I know the tests. I like the silvertips.
