Hey tankies,

I'm looking for a weapon that does the most damage from a single projectile in the game, and friends tell me it's the RPG-7 down in Aim Point. The description says it does 13 damage, but someone who owns one told me it can do 6-25 damage because of the explosive effect. So I'm confused on how this weapon works. Does it do 13 damage on average and 6-25 is just the range of numbers it can deal? What happens if the weapon becomes rusty, does it only do 6-24 damage then? Help would be nice, I'd love to have this novelty of a weapon.
