which ammo to take

[Crimson King]

5mm jacket hollow point or armor piercing for my assault rifle?

Depends on your Target. Deathclaws - hollow point, Power Armor - armor piercing.

[Crimson King]

deathclaws,rats,mutants?

I happen to know that the armor modifying ammunition does nothing the JHP ammo cannot do in Fallout 1.

Ammo modifiers are supposedly bugged, meaning that there's absolutely no difference between ammo types.

There is at least a special ammo patch here[www.nma-fallout.com], though it's also included in Fallout FIxt.
