Has anyone used the JLK 105s in a 6BRX. Would like to know how they shoot. Also, what powder were you using? I was thinking, if I put thousands of dollars in a rifle, I shouldn't be skimping on bullets. They are only a few dollars more per 100. I am a true believer in Sierra 107s but I want something a little more consistent. The barrel is a Bartline 1/8" 30" long. It has a freebore of .104.
