UPDATE...I ultimately sent my 42 in to Savage for service. I just couldn't get the rear sight to adjust low enough to have a sight picture at 25 yards (the useful range with these sights)
I was told they found a burr and sent it to the gunsmith had resighted it and it was returned to me. No charge for this.
It is no better than before. 25 shots at 25 yards all 6 inches high with 6 oclock hold!
I will be contacting Savage again. This is just not acceptable to have a close range gun like this that can't be aimed inside 50 yards.
I'll post with Savages response.
