Gta 5 Sniper rifle no animation while loading next bullet bug

It can also work without taking cover. I discovered this when i was still with my old computer, and tried to make a video about it but in the end of the process the video was laggy as fuck so i deleted it. I don't know if there's someone else who has already found it and even uploaded it on Youtube besides me, but since i don't see anyone i guess it's my discovery. ¯\_(ツ)_/¯
