For starters don't pick a rifle just because someone says they like it or it pawns. Remember that in most cases the L96A1 and it's varieties are the only rifles that will 1 shot kill unless you get a head shot. So bare that in mind when you choose a rifle based on accuracy and rate of fire. The SVD delivers a decent punch and has a good rate of fire. Some people don't like the reticle though. The SR25 is rather weak but is kind of accurate. Plan on needing 2 shots to kill. The MSG90 is just as accurate as the SR25 but is more powerful. You won't get too many 1 shot kills but it's a fairly easy rifle to use and can serve as an all purpose weapon because it's also semi-automatic and does not unscope. This is a decent sniper rifle for CQB no-scoping. So out of all the rifles I favor the MSG90. If you'll notice when you're scoped in your scope is swaying slightly. Don't try to counter it too much for a shot. Unless you're rushed by incoming sniper fire take your time. Let the reticle pass over your opponent before you fire. Sudden movement of the scope will cause you to miss. If you get the reticle within the general area of the opponent fast enough you should have plenty of time to allow the rifle to fine tune its own aim with that natural scope movement.
