Having read this thread yesterday, and having never taken the time to try Wolf or S&B ammo before, I took my 9mm CZ-75 to the range and figured I'd give all four a test. I shot each as 115g FMJs.
In my opinion, the Fiocchi proved far superior to the other three. Accuracy, "feel", and performance all seemed to be in favor of the Fiocchi. Firing mixed clips with the first 5 rounds being of one brand, the second 5 another, and the final 5 of another, I went through a box of each brand of ammo. (I also brought a box of 9mm FMJ Winchester USA with me).
My observations were with MY gun and MY shooting eye (your's may vary), the Fiocchi was truest to the center point of my five shot bursts--on a left to right axis, the Fiocchis varied the least. Wolf almost invariably wandered left of center but at least they were consistent. The Blazers also seemed to wander left and were consistently above my aiming point. The S&B were similar to the Fiocchi but varied a bid wider than the Fiocchi did.
The Wolf and the Blazers were filthy when it came to judging cleanliness. I took a 9mm Astra with me and shot a 10 round clip of each brand of ammo through the pistol. After each clip, I cleaned and swabbed the barrel with Hoppe's #9. I then dried the barrel and fired another brand. In order, the Fiocchi was cleanest followed by S&B. The Blazer was a distant third and the Wolf was without doubt the dirtiest ammo.
The Wolf brand also had a marked increase in muzzle flash and smoke after a round was discharged.
As to the "feel" of the rounds as they were fired, the Fiocchi had a crisp recoil--I felt as though I had fired a potent round. The Wolf, because of it's markedly more noticeable muzzle flash and powder burn, gave the appearance of performance without the heightened sense of recoil. The Blazer and the S&B felt pretty much the same as one another; there was nothing to distinguish them from each other. Recoil was minimal (which improved target acquisition), but they weren't much of a 'thrill' to shoot either.
Since the thread was limited to those four, I'll only comment on their specific performance. However, I will add that at $10 a box for the Fiocchi compared to the $6.97 that WalMart sells Winchester USA's for, I'll take the Winchesters over the Fiocchi and out perform all the other four for less money...
Just my observations, but I hope it helps. It's not scientific, it's just a guy who shoots for fun's one day experience.
