I could probably GECK it myself, but if someone has already done it, I don't see the point in bothering. I found these two mods on Nexus:

http://www.newvegasnexus.com/downloads/file.php?id=36554

and was wondering if anyone has used them. All I really want to do is to be able to craft pretty much any available ammo in the game, and I'm fine if it requires the hand loader perk and/or a high repair stat. I think that both these do that, but the descriptions aren't entirely clear to me. Anyway, if anyone has any experience with these mods, I'd appreciate some input. Thanks.

I use http://www.newvegasnexus.com/downloads/file.php?id=41013, it covers every ammo type. Explosives too.

You either have to find/buy schematics or take the appropriate perk (hand loader, etc).

I went with that one (ACS). However, it pretty much renders the hand loader perk useless as the schematics are easy to find and include the hand load rounds.

Regardless, I'm pretty stoked about being able to craft HP/AP/+P ammo.
