As for the LMG profile, rather than making them identical to the Automatic Rifle profile, maybe consider making them do flat DPS over all ranges? To get the DPS, add the minimal damage with the maximum damage and divide by two:
DP-28
3.6562 + 5.6875 = 09.3437 ÷ 2 = 4.6719 DPS
M1919 Rifle
5.3334 + 7.9727 = 13.3061 ÷ 2 = 6.6531 DPS
M1919 Para
5.7407 + 8.1806 = 13.9213 ÷ 2 = 6.9607 DPS
MG 42
5.6672 + 8.2389 = 13.9061 ÷ 2 = 6.9531 DPS
(I rounded up, all DPS's ended in a 5)
