I don't have a huge amount of experience with bolt action rifles (I tried it but it's not my playing style) but one thing I'll add is that sniping isn't just a case of sitting back our of AEG range plinking people. Being a successful sniper involves alot more fieldcraft so don't be surprised if it takes you a while to properly get the hang of it.
Don't get me wrong, I'm not saying don't do it but it's quite common for newer players to buy a bolt action rifle, only to be selling it a month or so later as it's not what they were hoping for
