Heya,
one stupid question: How do i craft the special ammo like Armor Piercing etc. It does not show up in my recipe list - is it even craftable?

I think there's a perk that unlocks AP/HP ammo at the reloading bench.

A perk? It doesn't give you the recipes when you level repair? I'd hate to have to use a perk on that.

Only some of the ammo recipes are available to the player. For example, you can't craft 5.56mm Hollow Point or Armour Piercing.

That said, there is a set of ammo called "hand load" that is unlocked with the Hand Loader perk. If you're a guns and repair character, you should definitely get it. Hand load ammo usually is the best ammo type for its caliber. I just got a sniper rifle, and the hand load ammo does x1.5 damage with no penalties.

Note that not all calibers get a "hand load" version:

and FYI dont really recommend about the case of sulplus(something like that) ammo....

case ammo gives you a lot of ammo.. but .. that.. whatever s .. bullet .. give to 3time cnd damage .. and slight dmg bonus..

i rather.. beat the enemies with Love and Hate then surplus.. ammo...

Mh but from what I've seen some of the ammos are quite awesome.

* .308 JSP Hand Load
o x1.5 Damage

* .50 MG Match Hand Load
o x1.15 Damage
o x0.65 Spread

Considering that the Sniper Rifle and Anti-Materiel Rifle are endgame weapons this is quite a huge boost...

And for those of you that love the .44 and trail carbine, getting the schematic for the .44 SWC is a must:

.44 SWC

1.2 dmg
-6 DT

Amazing.

Here's how you get it:
