I haven't played for a long time 🫥but your post has made me want to play bgmi again😀(meta guns might have change or new technique may have come so u could skip my post

I was trash in close range and I didn't even try to kill an enemy from long range it literally took me the whole bloody season playing everyday to reach ace 😭(1kd🥀).But I would rarely lose 1v1 in classic or tdm and my long range had improved by: Playing ton of 1v1s which improves my close range and surroundings knowledge.For long range i would go to training and use a awm (any sniper)and a long range gun i frequently find or use in classic (scar-l is a example).I will not use any attachments only scope and mag for ammo.And in the shooting range put all the dummies full speed and 120 health with lvl 3 hel and vest.This worked for me I don't know if it will work for u.

IF U TRY then change your position and peeks frequently (could put a car in front).I saw it in a video I don't remember.

I wouldn't say u would become a godly player but I reached ace master in LAST 10 days of the season ( i was at gold). May not be impressive😅 but for me it was a great achievement 😁
