SSK has non Destructive Device exemption for a 14.5 MM (.585″) cartridge.
The 14.5 MM JDJ is based on the 50 BMG case. The neck is opened to accept the SSK 1173 grain bullet loaded over 235 grains of 5010 to fire form the case. Other bullets may become available in the near future.
In the test rifle 100 yard accuracy hovers between .3 and .5″ with this fireform load. Velocity is chronographed at 26–2700 feet per second with the 1173 grain bullet. My worst 300 yard three shot group with it is 1.509″. The 750 Barnes is a real performer at 3000 FPS. Dies are in stock. Actions suitable for the 50 BMG are the ONLY ones that will take this cartridge. We recommend McMillan actions. Guns are all custom built according to customer preferences. It is doubtful that it will be possible to build one for less than $5,500. Please do not email questions—if seriously interested call–740-264-0176.
