In fallout 3 and New Vegas bullets can actually curve or shoot in a direction they shouldn't based on a dice roll (on top of the normal bullet spread). This mod removes that while maintaining the other RPG elements of shooting like bullet spread based on skill levels. Also the issue other modders have ran into with the guns not being aligned properly is avoided. Another effect of this mod is that your crosshair will turn red at a much larger distance when pointed at an enemy target, allowing you to tell friend from foe easier.

Did you verify that it's limiting aim to the center, rather than along weapon geometry?

yes, because I never turned autoaim off, I only changed how much it works to almost nothing. So it avoids the aiming bug.

Awesome! Just making sure

You rock!
