The .375 SOCOM is a fairly new cartridge, designed by Tromix in 2013. Taking a .458 SOCOM cartridge case and sizing the neck down to .375 caliber, resulted in a hard hitting AR-15 compatible cartridge, that has a considerable velocity and range advantage over the .458 SOCOM as well as other big bore AR-15 cartridges.

The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J), [1] similar to a light .45-70 but with a much smaller case.
The advantage to this round is the ballistic performance is nearly identical to the .300 Winchester Magnum [2] in a lighter rifle with a shorter action burning 8 - 10% less gunpowder. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of ...
