Pros and cons

Pros:

• 30 rounds loaded, can last an entire round with good trigger discipline.
• One hit will usually either directly destroy a single engine fighter or damage it enough to prompt the pilot to return to base

Cons:

• Very slow muzzle velocity, requiring a lot of lead to score a hit in a dogfight
• Self destroying HE shells, which limits the range at which they can be used.
• Absolutely useless AP shells, which struggles even with light tanks.
• Very slow rate of fire
• Inaccurate
