.45 Raptor Chambering Now Available

Tuesday, February 13, 2018

X-Caliber is pleased to announce, that in addition to our numerous other chamber offerings, we are now chambering barrels for the .45 Raptor.  Based on the .308 winchester, this cartridge offers the advantages of plentiful, economical brass to form cases and uses the readily available bullets and load data for the .460 SW.  From the .45 Raptor website:




  1. 460 SMITH & WESSON MAGNUM load data that has been pressure tested, validated and published by Hodgdon, Accurate Arms, Western Powder and other companies that list maximum chamber pressures keeping within a limit of 62,000 PSI – the SAAMI Maximum Average Pressure of the 308 Winchester which the larger AR series of rifles is engineered for.                                        
  2. 460 SMITH & WESSON MAGNUM reloading die sets with the only exception being the use of a 308 WINCHESTER shell holder.   Currently, Hornady, RCBS, Redding, Lee and Lyman offer 460 SMITH & WESSON MAGNUM reloading die sets as standard products.                                                                                                                                                                             
  1. 460 SMITH & WESSON MAGNUM bullets.  Hornady, Speer, Sierra, Barnes, Nosler and Swift all make bullets suitable for the .45 Raptor


"The 45 RAPTOR is designed to shoot bullets ranging from 160 grains up to 395 grains giving end users a wide range of projectile options to meet their specific requirements.   Whether that is a 185-grain JHP for target shooting or soft targets with minimal recoil, middleweight 200-250 grain bullets ideal for medium game animals such as deer or hogs or a 300-grain heavily constructed bullet for maximum energy on large game animals.  In actual field hunting tests on Feral Hogs, many bullets expand to .625”-.675” and retain 60-70% of their original weight."


We are excited to add this chambering to our lineup. The oustanding ballistics of the .45 Raptor combined with the excellent accuracy of an X-Caliber barrel make for an unbeatable combination.  For further information go to;
