Try to adjust the tall and wide values too. As long as you're not on a really strange res HUD crosshairs should be perfectly accurate if you adjusted them right.

-doublepost please delete-

The other post is about adjusting its size,and thanks

The wide and tall values in hudlayout.res shouldn't change the size of your crosshair.

adjust them to the small dot xhair, it's perfectly centered on the central four pixels which you should be aiming for
sometimes though you can't really get things pixel perfect, just REALLY CLOSE. this is the best I could do on mine.

Looks about right, but (especially on a darker surface) you can see the black sides are to the left and the white circle's to the right a little and the TFlogo is down-right a little.

i just zoomed in with sniper and adjusted them from the sniper dot.

that looks sick. where'd you get it?

I made it myself with Fog's xhair font (might be mistaking names)
It's great for most weapons but it's a little awkward with ones that are perfectly precise hitscan (basically, sniper rifles)
I can post the relevant lines if you want me to

please do

Let me know if I made an error.

thanks everyone, I think this is as good as its going to get/ needs to be , its really just there as a guide to where my scattergun bullets will hit.

I think you could get it better by changing the font size slightly.

this one?
"xHairDot"
{
"1"
{
"name" "Courier New"
"tall" "7"
"weight" "0"
"outline" "1"
}
}

Hey that's like my old crosshair before my hud broke. Best multi-sticky sniping assistant.

idk if the proportions will be correct (likely not) but if you set it to 8 or 6 then the central dot will be an even # of pixels large, so that it's center able
don't know if the HUD will give you Just The Right Spot though, it might be worth using 9 small dots instead of one dot matrix character if you want a perfect xhair, I'll stop now.
