I have the same press, plus the excellent Cast 4 hole Turret version with auto index that actually works. I've had the equivalent of yours in aluminum and frankly, apart from the 'feel' of cast vs aluminum billet, the aluminum was every bit as good, and a lot lighter to move around. Richard Lee defended the aluminum as stronger than cast steel and made the point that cast steel had to be thicker and heavier to attain equivalent strength. He conceded to his sons desire to offer cast steel not because of a material deficiency in aluminum but for perception and marketing reasons.
I'm not the best person to answer your repeatability question from a factual point of view as I don't bother too much, yet, with miniscule bump adjustment details. I can't see how the Lee press would be any less in this regard than a Rockchucker for instance or a Redding Turret etc. Maybe a Forster coaxial press would shade it but someone else can weigh in on that.
What you might note is Lee offers the breech lock insert with an integral locking ring with grub screw instead of the rubber ring system in the lock nuts that come with their dies. The said BreechLock insert replaces the original die locking ring and you set it up, tighten the grub scew and you have a permanent replicable setting. Buy one of these locking inserts per die.
Do put a small lead shot under the grub screw tho to protect your die threads. Have fun.
