Not sure about a 4000yard sniper rifle, but for any of you that venture over to Snipers Hide.
There is a thread regarding a new PRIVATELY FUNDED rifle/bullet that... Quote:...will shoot a 1,690 grain projectile(GS Custom Bullets) at 3,350 fps and the projectile will remain supersonic out to 5,000 + meters. Accuracy is .5 MOA to 3,000 yards.
That's roughly a 15" group at 3000yards. It is NOT a sniper rifle, and is NOT meant for shooting soft targets. Its an Anti-Material rifle, for shooting trucks, missiles, tanks and other large such targets.
They go on to say that the barrel life is into the thousands and each cartridge is in the $13-$15 range.
Rifle is called the 14.5mm OPS and the 1690 grain bullet possesses a B.C. of 2.118 and is solid copper.
Its entire weapon system is broken down into two pieces to be carried by a two man team and it comes in between 40-60lbs. They are working to reduce the weight even more.
The recoil is reduced with a recoil reduction stock and they are having a suppressor built.
Pictures are still pending on the rifle itself, but here is the projectile.
