Recently picked up one of those ER Shaw barrel kits from Midway in 7mm-08 & put that barrel on my model 11 308.
Before mounting it, I gave it a REAL good cleaning, including some patches of FITIZ to help smooth any rough edges. (or whatever that stuff is called)
When taking it out, I shot it a couple of times, then cleaned. Did this for the first 10 rounds.
I did have one group of 140 GK shoot into a 1.3" group so I'll start from there. This may work out to be a good shooter.
More updates as it progresses.....
