Different bullet drag value on some weapons

Hello, on some weapons, like M1903, BAR, M1909 and 10-A Slug bullet drag value is 0.002 instead of 0.0025. So, if it isn't an error - does it really matter, especially for M1903? Is it something like SSR-61 vs M98B in bf4(better gravity vs better muzzle) or difference is too small to rely on it?

you can use this to judge yourself.

The values are correct (can be seen in files). Relatively speaking 0.0025 is 25% larger than 0.002 which I would call significantly different.

In actual game it should have significant impact on drop, but I figure this is often combined with higher muzzle velocity and whatnot to create different types of curves.

yeah it is miff, but i still don't understand why giving the springfield values that only make it better past 250 meters, when dice has always been against playing past that exact distance... it doesn't make much sense to me.

Thanks for the link and for answers! This forum is amazing!
According to that graph - I should take M1903 only if I want to snipe past 300m and the difference is still very small until ~450m. Seems like the difference is not the same as in BF4, where SRR-61 had 620 m/s muzzle velocity and 6m/s2 gravity vs 650 m/s and 9.81m/s2 for M98B.

I have calculated the sensitivity of the trajectory with different air drag coefficients for the rifle M-1903.


As can be seen, the two coefficients give differences of less than 4 cm up to 300 m and 17 cm approx. at 500 m. Using the half head (14 cm) as measure of tolerance, up to 450 m there is no difference.

The role of air drag in the game does not seem to create different balistic characteristics for different weapons, but to prevent the use of sniper rifles at very long distances (> 600m).

At regular distances in the game ... forget the air drag.

And since 0.0025 variant(Gewehr 98 ) has 880m/s muzzle velocity - the difference become even more irrelevent.

The lower drag makes a big difference when shooting at pilots.
