Farming techniques

[Knights7.7.7]

Any farming tips you guys do on gta 5 sp? Here is mine, I usually go to the end of the tunnel where the jewel store heist exits and wait till nightfall. I'm guessing it is 6pm in game time. And wait for the gangs to spawn there. You can use the terrain to quickly headshot them whle maintaining ample cover. Retreat if you got a wanted star or two. Preferably use a vehicle behind you. Here you get a pistol, 12-25 usd in drops by enemies (not guaranteed everyone would drop) the wait for a minute outside the are for them to respawn. Rinse and repeat. You can raise your shooting, gain a few bucks, and a pistol.
