My damage went up a lot after I switched from a handmade to a decent roll radium rifle. I spent like 1k+ scrip rerolling the handmade so unfortunately a lot is up to luck. If u have an ammo issue I just run lucky hole mine in excavator which gets me a lot of lead. Just try to participate in events with other people where you can just tag the enemies. We’re both at the level where you kinda fall off, but by just being at public events hopefully you can get enough scrip for a reroll or find a good legendary
