Grand Theft Auto: San Andreas

[Danked]

A good place to amp up your weapon skills is in any police station. The large one in Los Santos is where I did this. You'll need a lot of ammo, but I was using the Weapons cheats and scrolling through all the weapons along the way. Just start wasting cops and even though you'll eventually end up with 6 warrant stars, you won't have to deal with the military taking you down.
