What is the point of having a semi auto long range sniper rifle..? The time of flight is greater than it would take you to reload with a bolt. You want the minimum going on in the gun to maximise accuracy. When they start making successful semi auto benchrest rifles, I might be interested..
..and before you ask, yes I know about the SVD - but even the Russians admit this rifle was always a compromise and not a true sniper rifle.
Oh - and stay away from those ********* on FPS Russia - their mummies don't know they are playing with guns..
