Yes Uncle H, I have got my .223 shooting like that now but I will admit that it is not a factory tube. My barrel isn't having the heat isssue after I switched to the 69 SMK and AA2495. I have shot a few 10 shot groups under 1/2" and then I shot my first perfect score of 200-29X. I'll post a pic of some 10 shot groups and my F-class target... You've got me going now Cranebird.
