I'm looking at having Krieger Barrel 1/8 twist chambered for the 6mm BRX with .145 FB............ I'm thinking this would work well for the Hybrid-VLD-Lapua-105's and Sierra 107 SMK with an overall chamber length of 1.555. I've decide on a .266" neck turn. Any opinions out there on the Freebore I'm planning on using?
