I've tried RWS Target Rifle, Eley Match, Eley Club. The closest I have had to the Wolf is Federal Ultra Match, but it's three times the price of the Wolf and not as accurate. I've also tried the usual: Aguila, Norma, CCI, Golden Eagle, Mini Mags, etc. etc. I have used the Wolf in my 455 Evolution, my 455 Thumbhole, my 455 FS AND MY 452 American. They all shoot the ten ring or X 25 out of 25 shots. Bottom line is that I have a lot of expensive ammo that will probably be used by my grandkids for plinking. I'm just gonna keep stocking up on the Wolf.
