It’s only overstated by degree. They mono bullets of yesteryear were dogshit and we’ve been promoted to just horseshit.
And yes, I’ve had hammers for close range meat hunts and one other use case. They’re terrible at mid-to-long range, in comparison to lead bullets.
Everything kills fine at close range and good velocity, including hammers and mono metals. It’s the edges of your range and intended use where you start to have problems. That area is when bullet choice matters.
And we’re got even getting into ease of establishing accuracy. Monos are finicky IME.
Here’s ELDx from my 7mm:

This is out of a 24” barrel 7prc. LRXBT gives you an extra 50 yards. Best you can do with monos. The lighter hammers would obviously be worse.
The reality is, if I want my range capped at 650-700 yards, I can shoot a 16-18” Creed with a sensible bullet.
