The IL-2 is the best GV killer in the game IMO.
The 23 mm guns are the most lethal airborne anti-GV guns out there, even better that 4 x 20 mm Hispanos, again IMO.
The big rockets seem to have a very big punch, close is good enough with them. They seem equal to about a 250 lbs bomb in GV killing power.
I regularly get 4 to 8 kill sorties in it.

Tour 20 - eskimo has 28 kills and has been killed 18 times in the Il-2.
Tour 19 - eskimo has 63 kills and has been killed 20 times in the Il-2.
Tour 18 - eskimo has 89 kills and has been killed 25 times in the Il-2.
Tour 17 - eskimo has 73 kills and has been killed 31 times in the Il-2.
Tour 16 - eskimo has 73 kills and has been killed 23 times in the Il-2.
My IL-2 advice:
Always take the big rockets.
Don't bother with bombs, the IL-2 climbs too poorly.
50% Fuel is always plenty, the IL-2 climbs poorly.
Avoid flying it when the enemy has air superiority. The IL-2 can fight, but it's a slow dog.
When engaging enemy aircraft, try to only offer them a HO, its got better armor and great guns.
Against GVs, be sneaky.
