Yet when I aim at a guys head I hit it no problem so I am guessing there is some kind of auto aim that helps align the shot for you.
Mmhm. The shot is actually based on a chance effect so you may be off target and it "bends" to the enemy or does the complete opposite. Of course, there's a http://www.newvegasnexus.com/downloads/file.php?id=34723 to fix that, and where I obviously got this info, and with it, it really depends on how well you can aim with the good old mouse and keyboard. It does make a difference... especially how I had installed this after 4 and a half playthroughs.
Yeah, the sighting being a bit high on the hunting rifle is due to an actual misalignment on the SightingNode itself. I have some fixed hunting rifle meshes laying about, I can REL them after work today.
Looking forward to it.
