Well that's what I was thinking, the FPE formula only takes weight and velocity into consideration, which would favor the higher velocity. But, as you know, bullet diameter (and nose shape) plays a big part in how a projectile kills...what I call "whompability".
I believe that a thick skirted minnie that outweighs the long .45 calibre slugs (500+) could be driven to equal velocities from a good sound gun...however there would be a penalty to pay in recoil from the bigger gun.
I turned the base plug down in the big 600 grain minnie mould I have, (perhaps it was a 580 before I did that?) and it seems to be fine with 120 grain loads which I have shot in the past but don't plan to do again. However if I had a reason such as a grizz hunt or African game I would not hesitate to put 110 grains under it.
Obviously with equal (or close) velocity and bullet weights the .45 would range out further and retain more energy at very long ranges...but within 150 yards I bet the .58 would WHOMP harder!!
That's my story and I'm sticking to it anyhow.
I believe the 60-70 grain service charge took economy of powder and recoil heavily into consideration.
