They considered it, but Alan said it doesn't have an effect at the engagement ranges for Stalingrad. So my guess is for rifles, it's probably not included in the calcs. I'd expect we may see it for tank ballistics.
From the way I read it, you can expect to see the transonic issues with appropriate SMGs and pistol rounds.
Oh I was only talking about the correct ballistic coefficients etc etc.. dunno why the "Coriolis effect" part was highlighted, was a simple copy paste from the site?
I love the fact that they will pay extra attention to ballistic coefficients this time around, will make German rifles & MG's more effective at longer ranges than the Soviet rifles & MG's, just as they were in real life.
The German rifles & MG's fired the 12.8 g (198 gr) FMJ boat tailed sS round, with a ballistic coefficient of .585 to .595 G1 (the latter being marksmen ammo without cannelure), whilst Soviet rifles & MG's fired the 9.5 g (147 gr) FMJ flat based M1908 Type L round with a ballistic coefficient of .393 G1.
At a muzzle velocity of 760 m/s the sS round reaches the transonic region at ~1,250 meters, whilst at 860 m/s the Type L round reaches the transonic region at ~1,000 meters. So those are pretty much the effective ranges of the rifles firing each round as the disturbance caused to flight path in the transonic region significantly affects accuracy beyond that point.
