Yes they will reach that far and further. If you research civil war weapons you will find that snipers of that era made shots of more than 500 yards. Todays weapons are very capable of making such shots. It requires a lot of testing on your part to acheive such ranges. I have personally taken deer further than that but never much more than 300. I do not recommend shooting at such ranges without a lot of range time. T/C and Knight guns you will find can be very effective at such distances. Like any other weapon practise makes perfect. I cannot speak for CVA but can for T/C and Knight. Groups of 2 to 3 inches and tighter at 250 are obtainable with a little effort.
