A hardcast flat point with a 75 to 78% meplat and proper nose shape will out penetrate any JHP and usually JFP bullets and leave a wound channel that looks like a JHP that ecpands made
Would you say you don’t see any advantage of even these Golden Saber bullets to hard casts?
It depends on what you need or want the bullet to do. Revolvers have the advantage over semi autos in that they don't have feeding issues and can have larger meplats.
Mackay_Sagebrush's 147 grain flat point hardcast definitely penetrates much more and leaves decent wound channels, judging by the 1 hog that I killed with them.
But there are situations that less penetration is desired. Definitely a place for both, IMHO
