CDLC S.O.G. Prairie Fire 40mm M79 Grenade Launcher buckshot has absurd trajectory

[aksuduud]

Mods (complete and add to the following information):

• Arma 3: 2.18.152405 stable
• CBA: v3.18.1 stable
• ACE3: 3.18.1 stable

Description:
M79 has an alternate firing mode for M576 Buckshot, in ACE the shot does not follow the 75m sights nor the 3D barrel line, instead it is fired at an absurdly high angle as evidenced from the screenshots. This behaviour only happens with ACE Advanced Ballistics disabled, without any mods the round fires as expected, and with ace + cba with advanced ballistics enabled it fires at only a slightly higher arc. Increasing the sight setting makes the problem worse, when the gun is held level and sights are set at 375 meters the shot is fired almost vertically, slightly behind the shooter.

Steps to reproduce:
Fire SOG Prairie Fire M79 M576 Buckshot and observe the bullet trajectory

Expected behavior:
Shot is fired straight, as without mods

Where did the issue occur?

• Editor (Singleplayer)
