458 SOCOM SBR bolt gun project is coming together. This started as a 6.5 grendel Ruger ranch. We had The Gun Fix open the bolt up a touch, open the forend up to accept the bull barrel, and headspace the barrel. This gun has been purpose built with a 1-10 twist to shoot the awesome 475 gr selous expanders from Discreet Ballistics Check out the last photo comparing the massive 458 diameter bullet to the 188 gr 30 cal 300BLK selous expanders.
