How many 500 LB bombs from a b29 is required to kill a base in Air Arcade?

I just unlocked the b29 and have begun using the 40x500 bombs for bombing bases I currently use about 20 per base I’m not sure if I should use less. Can some one help me get the right number?

Depends on BR of match. You get a reload anyway.

EDIT: its the 7.0 BR cause b29

It should be around ten 500 lbs bombs in 7.0

ok thanks alot man!
