Hey guys. I have CFWNV and I followed all the instructions, but there's a problem. See, when I have for example an M1 Garand, I can't use ammo for it. I'm able to fire it (sort of, it makes the firing animation and the sound, but no shells fly out of the ejection port and when I try to reload it puts the gun away). I see NPC's with the guns and ammo in their inventories but they don't fire them. I think it's a problem with CaliberX but I dunno. anyone have any experience with this? here's my load order.

I'm not sure CFWNV, Caliber, nVamp, and Arwen's are compatible. Arwen's is an overhaul mod, and makes changes across the board, including to weapons and weapon effects (such as her blast, whack, etc). Arwen's also includes a feature to handle threshold, rendering True Threshold redundant (which may cause other problems right there).

As a test, i deactivated all my mods except CFWNV and I still wasn't able to use the guns. I dunno what could have happened, I mean I'm pretty sure I followed everything to a tee.

CFWNV requires CaliberX, which must be installed first, and then CFWNV is installed, with it's own custom CaliberX stuff. With just those installed, it should work perfectly.

I had CaliberX too, why it doesn't work I dunno. Maybe it's because I didn't FOMOD them. Trying that now, will report back.

Okay, it works now. Thanks for the responses though. I just had to FOMOD them, which I stupidly didn't do.
