When the first factory swaged round balls hit the market they were great. All in the box the same size and weight and round. As the companies used their swaging molds the molds started to wear and produced balls that were not round and of different size and weights per ball in any single box. At this point guys found they could cast better balls then the factory swaged balls.
Then the companies made new molds and started to produce nearly perfect round balls again. I believe this runs in a cycle as the molds wear and the companies replace the molds so it seems to me that judging the comparative quality between hand cast balls and factory swaged balls would depend on what part of the cycle the factory molds are when you make the comparison.
I think the companies that make swaged balls have a better hand on quality control and and have set a standard for what is acceptable, but they still probably wait until their molds are producing substandard balls before replacing their molds.
Now, all of this probably makes little difference for the casual shooter, plinkers and hunters, but for serious target shooters they might think about checking and weighing any swaged balls they purchase.
