For that you'll have to mess with the menufile for it. I think that's JR-Imagine's HUD right? In any case it's going to take a bit of messing with as this: AMMO | STOCK is handled by an ownerdraw and not split apart. I do remember that messing with the 3rd parameter of rect of that itemDef did space it out I think, don't recall for sure I'll have to mess with it again myself. I'll get back to you real quick.

Edit: Okay yeah so you can space out the text by the 3rd parameter of rect like I thought.
(Image removed from quote.)
So look for something that's similar to that or more specifically
ownerdraw CG_PLAYER_AMMO_VALUE
or
ownerdraw 5
(5 = CG_PLAYER_AMMO_VALUE)
And once you do in that itemDef {} block change the 3rd parameters value (increasing) and it'll space it out.

Edit 2: Sadly the scoreboard thing you can't modify I could try figuring out the font and remaking this entire font thing to work a bit better but I won't do that now.
