The Cal50 bullets do their damage primarily through inertial energy, they lose effectiveness dramatically over that distance and they scatter a lot more. Convergence at 300m means that a lot less bullets actually hit the convergence-point than at 150m range.

The .50s hit great and they do quite a bit of damage period.
The challenge with them is their accuracy in the game. Wheather it's right or wrong it really doesn't matter but the fact is they aren't very accurate far out.
We have people admitting the .50 calibre is not accurate at range, here is the first example of why the modelling is wrong.

Anyone who has bothered in the slightest to look at ballistics and how slug design affects it will understand that the .50 calibre round has excellent accuracy characteristics over distance.

There are two main reasons for this.

Aerodynamics in a projectile shape require a tapered, sharp pointed tip, and a 'boat tail', or tapered rear, with the taper starting at about the mid point of the round and extending to the rear, for maximum efficiency. The .50 calibre round satisfies both of these criteria.





That is in contrast to rounds such as the MG151/20 or Mk 108 whose ballistic aerodynamics are very poor. Both of these have rounds with flat noses, and no boattailing to the rear. The Mk 108 is the second from the left below in the first photo, and the MG151/20 (20 X 82) is the fourth from the left in the second photo.





Rounds with poor shape will lose speed much faster, and diverge from their path more often.

The other major factor in ballistic efficiency is muzzle velocity. The .50 calibre round has a muzzle velocity of 880 meters per second compared to the MG151/20 at 725 m/s and the abysmal Mk 108 at 505 m/s. The Mk 108 will suffer a bullet drop nearly twice as far as the .50 in the same distance.

All of these factors combine to give the .50 cal a much better accuracy at range than these other two weapons. So to find that the .50's are less accurate at range in the game has to raise questions.
