Actually, that is the beauty of cast bullets, you can make the bullets do anything you want.
by adjusting the alloy and how it is made, you can make the cast equivalent of FMJ to partitions.
The neatest tech I have learnt about is probably 150/200yrs old. This is making softnose cast bullets. Way back when, they also had concerns about their cast bullets not expanding enough on 'soft' game and in smaller cals.
So they figured out how to put a softer lead 'top' onto a hard alloy 'bottom'. You make the bullet in two stages and you get a slug that expands rapidly on impact yet retains a hard base to blast through big bones if encountered.
You can also adjust the amount of soft nose vs hard bottom. Exactly what SWIFT did with its A-frame hunting bullets and what Nosler had to recently do to appease the retained weight crowd.
Voila, partition performance you can make in your backyard. Accuracy is no different then a single alloy slug.
some have reversed the process to ensure proper bore seal when using really goofy barrels and not having hollow base molds.
Then there is paper patching which gets you into some pretty impressive velocities, gas checks, hollow points/bases, different nose shapes, grease grooves, and on it goes.
Pretty soon, you are thinking about custom molds and crazy wildcats, indexing bullets and dies, all sorts of sorting and weighing, making your own super lubes, special cast bullet barrels and sub MOA accuracy.
Honestly, best if you don't get started...
