Instead of opening up inventory scramble to find ammo for your weapon then click it then choose to attach.
How bout, run out of ammo, press reload, a little pop up window with ammo for that gun, highlight which you want, hit accept and reload.
Im on xbox x
Yeah, this really needs improved. Ideal situation IMO would be:
Hey. I was thinking about something similar to this last night.
My thoughts were to change your ammo type, hold the reload button and choose which one to load.
I think that should be feasible to implement?
@ahferroin7
Switch ammo by keybind, I suggested this in a different post.
But slightly different: hitting that key would make you instantly load the new desired ammo typeā¦
So, example: Bind Key U to ammo type X, Bind Key to ammo type Yā¦
Hitting U thus would immediately load ammo X
I really like this ideaā¦
Who knowsā¦ maybeā¦
Another one I suggested: weapon display (weapon in the quick-bar) auto-shows ammo (and maybe mods) loaded?
Good thinking right there, @Thierry_Onwed @ahferroin7 !!!
Iād like to second the suggestion about having a keybinding to switch ammo - however my idea might be even simpler.
Many games have a single keybind to switch ammo on the fly, that simply ācyclesā through available ammo types for the equipped weapon (STALKER games are a good example of this).
So for instance 9mm have FMJ and AP ammo. Hitting this single key will load the first stack of the āotherā ammo type than what is currently in the weapon. If you have 3 ammo types, it will cycle through all 3.
This is IMO the fastest and easiest way to implement an ammo cycle key, and you only need a single key or button. And 99% of the times youāll only have 2 ammo types to switch through, which makes it very simple and intuitive. 
It would also be nice if the HUD more clearly showed what type of ammo is currently loaded in your weapon, I donāt believe this info is clearly shown atmā¦
Issue is with consoles, they do not have free buttons.
And PC as well as consoles basically have the same game, save for the engine.
Bringing it it PC should also bring this to consoleā¦
Why not enable button combinations for consoles?
Use the same key as the fire mode switch and add a modifier key.
@pegnose
I suggested this actually, but seems to be too hard for the players, I was told.
Accidentally hitting more keys and all.
Could be, not familiar with these devilish monsters.
When I see one, I ask Geralt to deal with themā¦
There is a popular game that Iāve put thousands of hours into that has a nice feature when it comes to switching ammo types. Normally āRā is to reload your weapon, but if you held down āRā it brings up a circle wheel that has the available ammo types for your current weapon in your inventory. Iām sure you could do something very similar with the common reload button on consoles. You would move the mouse (or joystick) to highlight which ammo type you want, and then your character reloads the weapon with that other ammo type. It works quite well and itās simple
Yeah, that would solve the console issue very elegently! 
@boston_51 @pegnose
If the console users agree, I am all for it.
Good idea.
Then again, key combo got shot off to, which imho was just as logical as idea.
Either way, love the thought for sure.
they should just add keyboard and mouse support for consoles
There are a million shooters on console that have this figured out. Itās not that hard.
