I don't understand this obsession with the SMG "ejecting rifle casings" 4.6x30mm isn't going to be the same length as 5.56 or 7.62 which is the mistake many modders end up making!
4.6x30mm case length- 30.50mm
5.56x45mm case length- 44.70mm
and given that most scenarios surrounding the SMGs (when used by civil protection anyway) the rounds are without a doubt going to be hollow-point rounds since those are better at piercing through non-armored targets... like the vast majority of resistance members tend to be.

Thanks for the heads-up! Just fixed it

SMG1 should have a rifle shell in them when ejected
