well using a gun that shoots hot means you have to get proper training, and we don't want new people shooting others with 500 fps from 30 feet away. The upgrading and investing alot of money on a sniper rifle is all up to you, when i got my vsr10 it was shooting 283 fps, and i had more kills then with my aeg, because it was quite and accurate. Shooting hot means you have a MED , medium engagement distance, can't shoot anyone closer then 200 feet if im not mistaken. Someone plz correct me if im wrong on any of these, To have a great sniper rifle you will need to invest alot of time and money
