The ammo is fine, quite accurate, doesn't leave a lot of residue on a gun, great for practice.
Subjectively, it feels far less powerful on recoil than PMC Bronze .357 JSP 158 Grain, despite that this
Armscor ammo is claimed to have 823fp of energy, while PMC "just" 759fp. The PMC 158gr JSP fired from 4.2" barrel GP100 with factory grip feels like sharp violent snap with nice fireball (after 50 rds arms feel sore), while Armscor fires more like .38 +P "pop" with mild recoil (after 50rds you can go another 50). Of course chronograph (which I don't have) to be the judge, all "feel" are subjective.
Regarding posts stating ejection issues - happened to me as well, on cleaned and dry cylinder after first 7 rounds 3 had to be bulled by hand. And this behavior persisted through all 50 rounds in the box - you drop some rounds, then pull those that stuck. Also, I mentioned after 50 rounds (load-shoot, no delay) the gun was not even near that hot than after PMC or Fiocchi, just pack it into a pouch right away without even need for cooling down.
The verdict - good for practice shooting and/or .357 wheel gun beginners. Other applications - better measure actual velocity with chronograph.

Shoots Great and Accurate
I've put 200 rounds of this ammo through my Rossi R92, 357 rifle with a 24" barrel. It shoots great and is very accurate. Highly recommend!

I expect my ammo to go BANG
I expect my ammo to go BANG every time I pull the trigger. 3 of 8 rounds FAIL to fire in my S&W TR8 Revolver when I use DA (trigger pull cocks and releases hammer). The primers are clearly struck. I've compared with 3 other brands of ammo that cycle flawlessly. My Henry lever rifle has no issues. I feel this ammo produces more smoke than others.

Not loaded correctly/possibly reloads
Several rounds were not seated correctly, and some even had different diameter casings. When fired, they would have varying amounts of gunpowder residue that were anything but consistent, and the casings would swell from the heat, making it a nightmare for revolver owners to eject.
