you mean this one? http://skyrim.nexusmods.com/mods/14125 and this; http://skyrim.nexusmods.com/mods/5388/ but the first is outdated because there's an ini line you can add to get the same thing wthout having t make compatibility patches for any bow mods. [Combat] bForceNPCsUseAmmo=1
the arrows and bolts mod should have this. you could also try adding this too your skyrim.ini so when you loot people they don't all have their full stock of arrows still on them.
