The .45 Raptor is one beast of a cartridge. Designed by Arne Brennan, the .45 Raptor is new cartridge that replicates .460 S&W Magnum performance in a package tailor-made for semi-automatic rifles.
When fired from a rifle-length barrel the ballistics put other big-bore cartridges to shame, including .450 Bushmaster, .458 SOCOM and even .50 Beowulf.
The .45 Raptor can be loaded with a wide range of bullet weights, from 160 grains at the light end of the scale all the way up to 395 grains at speeds up to 3,000 feet per second. Depending on the load that translates to in the neighborhood of 3,150 foot-pounds of force to upwards of 3,500 foot pounds.
