Extreme Long Range-Sniper Rifle

United States Special Operations Command (USSOCOM) is seeking to replace older anti- materiel and anti-personnel rifles such as the M107 and MK15 with a newer system. This Sources Sought Notice will provide valuable market research on state-of-the-art sniper systems. Interested vendors must provide their submission through Marvin Marcia marvin.marcia@socom.mil.

That sounds fun...

Just join our sport called King of 2-Mile where we are currently shooting out past 4400 yards and making consistent hits on target. There are other groups specializing in ELR competitions in both Light and Heavy classes.

Barrett has probably already won that contract with their release of the MRADELR rifle system available in multiple cartridges like the 416 Barrett which is a shortened 50BMG cartridge.
Other rifles could be better like the Cadex but Barrett has the lock on the market (I personally would like to see Barrett knocked off the platform).

I presume that portability means that 20mm like the Anzio is out. Rule Of Cool though:

Is the Cadex better than AI?

My 50BMG target rifle has a 38" SS K&P cut-rifled barrel - it looks long compared to the 29" stock barrel.
Some of the ELR shooters are using 42" barrels and most manufacturers have up to 45" as the maximum length available.
The barrel in this picture looks long because of the added suppressor length.

That projectile looks long as in a long bearing surface.

My Match style cartridges are also long. Case body is 3.905" long, Projectile is 2.699" long, Driving band is 0.150" long, Boattail is 0.375" long, Driving band diameter is 0.5105", Bore-rider diameter is 0.502", Barrel bore diameter is 0.498", Barrel groove diameter is 0.510", Distance off lands is 0.030", Projectile is seated into case body about 0.160", Bore-rider diameter sets into special cut lands of 0.5030" diameter of chamber/throat, Y.M.M.V.

2.699 - 0.375 - 0.150 = 2.174" Case length 3.905 + exposed projectile length 2.174 = 6.079" - 0.010" seating depth variation = 6.069" actual cartridge length as compared to the military standard for this cartridge being 5.450"



Please note I don't like to use the term "BULLET" as its definition has been abused by so many as to make determination of actual use seem to be the total cartridge assembly, and to some, as myself and other hand-loaders, the projectile which is loaded into the cartridge assembly.
