Ahoy, welcome, and yup, /thread, basically. It's best not to change too many things at once, as then you'll never be sure what's helped, done nothing, or made it worse.
Maple Leaf Macaron 60 plus an "omega" style nub is my go-to. I've messed around with flat hops, R-hops and S-hops but why bother when the Maple Leafs do such a good job?
This combination, although ak2m4 is off this week and not taking orders:

Opinions will vary and you'll see 50 suggested (especially in colder weather when the rubber will be harder) or 70 (from Johnny Abroadlander where it's scorchio). I've tried both without noticing much of a difference at UK power levels, so now just stick to 60.
While you've got the barrel out, give it a through clean through using a rod, cleaning patch and isopropanol or your solvent of choice. You'd be amazed how much oil and grease some barrels ship with, and they can spunk more badness down there over time from whatever's coming out of the cylinder or magazine.
That'll help accuracy / consistency. Ultimate range is determined by the muzzle energy, which is a different subject. But if you're getting anything between 1J - 1.13J using 0.28g BBs (or as heavy as your hop can lift and your wallet stand) then you'll be competitive with anyone else. It's rare that those last 2 or 3 metres of range really matter, compared to having correct and consistent hop applied.
