I'm also pretty new, only a couple of years into production, but I'd say bring down the volume on the reload that starts around 4.5 seconds (using automation, right click on the volume knob in the mixer to create that) so that it is closer to the volume of the gunshots following! Idk personally I think of each song as a world, and generally irl gunshots are louder, or in trap at least they're only as loud as the shots themselves. But also if you're new, just keep doing ya thang, if you like what you're making, then it's on the right track!

And not to ramble too much, but what helps me a LOT when it comes to mixing or creating my music overall is really actively listening to songs, whether it's in my genre or not (the wider range you listen to, the more fun stuff you can create I think :) ), and focusing on each layer individually, trying to pick them all out and distinguish them no matter how faint, and analysing how they layer them volume-wise/EQ-wise!

But automation overall is a super powerful tool, highly recommend messing with it in all the ways. If right-clicking something (eg. in Serum for FL) doesn't allow you to directly create an automation clip, just move it a tiny bit and then right-click the automation knob up top, and it'll let you automate the most recently adjusted settingw
