Patience and Time is hands down best sniper in the game because it has next to no recoil and you get a free headshots if you wait for camo to activate whilst behind cover like you should with a real sniper rifle. Basically you find a target hide then aim wait for camo pop out and bang target dead . Rinse and repeat until all targets are down . Just make sure you have special ammo synthesis and you really can't go wrong with this rifle. Btw icebreaker kicks like a mule compared to P&T.
