Would like to get opinions on a light weight (2.5 to 3 lbs) barrel for a carry gun. I like 308 cal and I'm thinking 20-22" barrel lenght. Would like to shoot 165's, sooo 1x11 or 1x12? I'd like to see 1/2 or 3/4" groups???.... Any recommendations on barrel makers that will install on my action? Thanks in advance!
