The Bushmaster gun shoots 25 × 137 mm ammunition, while 2A72 uses a larger ammunition - 30 × 165 mm. Experts say that, at first glance, it seems that the installation of a larger and firing gun can give an advantage: 2A72 makes up to 330 shots per minute against 200 in M242. However, it is not so unambiguous. The fact is that 2A72 demonstrates low stability when firing: the trunk actively vibrates, which reduces the accuracy.
In addition, the Soviet cannon is inferior to the American in the quality of armor -piercing shells. For example, Bushmaster M242 is capable of using M919 ammunition with a depleted Uranus, which shows a high piercing ability even against heavy armored vehicles. 2A72 there are no such ammunition. According to Analytics, Defense Express, the main reason for replacing the gun may be logistics.
Russia does not have large reserves of 25 mm ammunition to M242 and original spare parts for American equipment. Therefore, even a partially damaged machine without the possibility of repair or recharge loses meaning in combat use. Replacing the gun with domestic 2A72 simplifies supply, but causes a lot of technical problems.
For example, to integrate 2A72 into the American Tower, you need to completely rework the ammunition supply mechanism, and most importantly, to upgrade the fire control system. In addition, both guns were produced with different sights, electronics and architecture. Therefore, with handicraft installation there is a situation in which it will be possible to shoot except "on the eye".
