Pepperballs
For when you get into those not-quite-spicy situations

How about we add a different kind of ammo for all weapons?

Pepperball ammo. Only available from ammocrafters.

It would target stamina only for non-lethal takedowns and sparring. Though it should damage as much as or close to normal ammo, so to say, and not be much faster or too much slower to take someone down.

Maybe add a pepperball popPop too.

Alternatively, the same but as rubber bullets and doing brute dmg.

If you search for new ammo types there a ton of older threads that seem to ask for the same thing over the span of years. Gives the impression that while cool this is probably so far down the list of things to look at, that I would not hold my breath on the idea. The double edged sword of gun usage though!
