Breakdown
Breaking down a standard .357 Magnum round yields:

.357 Magnum, hollow point
Hollow point bullets are designed to mushroom out, expanding up to 5 times their original size resulting in a jagged, gory wound much larger than the actual round. Hollow points lack the penetrating power to punch through denser materials due to the fact that their force is distributed over a larger area, drastically reducing the weapon's penetrating power. For that same reason, they are excellent at turning internal organs to mush.

.357 Magnum, JFP (hand load)
JFPs (or jacketed flat points) are blunt, copper-wrapped bullets designed to flatten on impact like a hollow point, but retain the penetrating power of a copper-jacket slug. As such, they inflict greater damage, penetrate enemy armor better, and even fly straighter than normal .357 rounds. They require the Hand Loader perk to craft.

.38 special round
.38 special rounds are a less powerful cartridge than .357 Magnum rounds. They can be fired from .357 weapons because the .357 Magnum was developed from the .38 special round, and they share all the same dimensions except case length. Though the reduction in powder means less damage inflicted on the target, it also means less wear and tear per shot on the gun.
