I've tried all the popular brands of ammo in my Baer (a stainless Stinger), except Wolf...and all of them are accurate...some more so than others, but not a single brand could be called anything near "spray".
With my reloads...I can hit Skoal cans at 50 yards, at least 3 times out of 7 rounds. (the misses are me, not the pistol)...and every once in a while I can hit 7 out of 7.
It could be the pistol...even Baer lets a lemon out the door occasionally (they all do).
With that said...its usually the shooter though. Without knowing your experience and ability, and not trying to offend you either...I'd say find somebody who for sure can shoot straight and let them see what they get out of it.
Then you'll know...
