Thanks for the great article. I am going to check with Criterion on a 22-250 barrel for one of my older rifles. I am pretty sure it is shot out and I need to replace.

Used to be a tack driver but alas it is starting to wonder around.

Have you tried to really clean the bore to remove all copper fouling? Also, might want to check the stock bedding.
