Some tests in-game with a dispersion = 0;, "Point of Impact" results top right of the screen:

• AA12 Slug, RC0, 300m: Default Ballistic, Advanced ballistics.
• SIX-12 Slug, RC0, 300m: Default Ballistic, Advanced ballistics.

The title means what it means, vanilla slug fixed, i just added a new one.
It was not a problem to add new pellets in the past (default ballistic WS pellet MV also fixed with this PR).
Title updated.

Remove #11280, has no effect on slug trajectory in-game and remove the possibility to play with Type 115 secondary weapon (50BW) with scope.
Update Western Sahara XMS SG shotgun realistic name SIX-12 (thanks to rekterakathom for his source).

These are out of scope for this PR.

• The vanilla and WS underbarrel shotguns are the same, i just added realistic name for WS. For 12 lines, i will not make a new PR.
• Your PR solves nothing, so useless. Would be useful to check your own PR properly in-game before merging it.

I have no doubt about your programming knowledge (i'm completely incompetent for that) and i have absolutely anything against you, but about ballistics you have probably some things to learn.

How to remove johnb432 as reviewer of this PR ?

Please tone down your language, there is no reason to get personal. Review comments aren't attacks on you and you shouldn't treat them as such.

This PR should be split up

I agree

• It's not a question of language, attacks, ego or i don't know what. My priority is AB, i'm focused on it since the 2014 stand alone, before ACE3.
  I don't want AB becomes an Arcadish Ballistics with, for example, a "NoScopes" fix or a "Hardcoded 50m zeroing" simulation. Again, that solves or improves nothing, the proof with this PR. The correct small caliber projectiles trajectory in-game with the both ballistics is the most important for me.
• Ammo and magazines have an effect on vanilla game and WS, the second slug depends on the first.
  As you can see, it's not a basic PR and it's better to be seen in globality.

As requested, Slug 300gr removed.
