Depends on your gun / sights more then the quality of the ammo for most users. Some rounds / weights tend to shoot right where the sights are, some may hit a bit high or low.
Case in point, I'm shooting "Novosibirsk Cartridge Plant" brand Russian Steelcase 115gr, that was about $0.15 per shot back when Wolf was $0.20, to give a sense of quality. Every 50th round or so produces an incredible, basketball sized flash...
And I'll be damned if my CZ's and Glock's don't love this load, shooting dead on with the sights / 5 rounds in a quarter sized, bullseye accurate group at 7 yards.
Meanwhile, the most accurate load in my buddy's Sphinx SDP is not his hand crafted reloads using premium bullets, which tend to shoot a bit low relative to his sights, but some 124gr Privi I lent him.
It's weird!
