I read you can improve your Shooting stat at the gun range. I am only interested in GTA Online here.
Can it be done solo or does that have no effect?
What do I have to actually complete at the gun range to increase my stat?
If I do a best out of 3 against someone how much does that actually contribute to my stat? What are the factors that will determine how much? Do I need to win?
I read that gold/silver/bronze medals give you 3/2/1% increase in shooting stat. I have never seen anything about medals when doing it online, it's just me against another guy trying to shoot targets. How do I/we get medals online?
