To me it just comes down to muscle memory and instinctiveness. Don’t try to overthink it too much while playing. I also find myself always glancing at the radar for split seconds and using that at a gauge on how aggressive I should be. If you play enough then you’ll get a feel on how people play depending on what they use and you can use that as a way to try and predict what will happen in certain scenarios. Popular weapons like fusion rifles, shotguns and snipers each have unique play styles. As for hand cannons, you’ll get used to them just by playing and learning from experience. Also for 140 rpms, the range you want is at least mid 60s. I also like higher stability (especially on controller). I hope this helped.
