Goal: Not to dump 300 bullets after Pier 69.
Method: Have a couple of rounds of ammo for a drive-by weapon left over after "My busting was tight". This way you don't get any uzi ammo at all ([11:22 PM] Lelresetfeg: " 1 bullet will be enough lads"). Code: https://pastebin.com/kiSLzWy9
For this, you need to have some ammo after Ice Cold Killa and then avoid shooting it despite holding a call. For that, you use The New "no auto-switch" glitch: Basically, if you cancel the "hang up phone" animation, CJ will not switch to a drive-by weapon the **one next time** you enter a vehicle.

Now the steps:
1) Make sure you have a couple of drive-by weapon bullets before the ICK final call (you can get Jizzy's uzi).
2) Make sure to hold the phone in your hand after that call (for that you need to be jumping as CJ takes the call, which is 2s after "phone collected").
3) Pay close attention to not fall off your NRG.
4) Start Pier 69.

*Now you want the phone to ring as you shoot the guys. That way, your shooting cancels the call and you get it again before you get on your NRG again.*
Steps:
5) end the call asap
5.1) Hold the call through the Pier 69 intro cs.
5.2) Press F (to run towards the bike) and **right afterwards** release the call button.
*Your phone rings before you start sniping.*
6) Do the snipes (cancelling the call).

7) Hold the next call and finish the mission.



Getting the uzi ammo during the mission *Jizzy* cannot be avoided this way. Your drive-by ammo is increased to at least 200 no matter how much you have.
