Gary, good to see you have solved out the problem with your A7. BTW, mine is in a 7 MM Magnum that sports a 26" fluted barrel. With hope upon getting it back from the gunsmith the groups will improve. One can only hope.
I have to say that I have sold too many very good shooting rifles that I should be horse whipped for doing so. The last was a Remington 700 SPS that had lots of work done and it shot sub one inch groups off the bench. This was in a 300WSM that I took to Africa on three trips and NZ in 2016. It became a safe queen and decided to sell it. Mistake! This is the Remington that I sold. It was a one and done rifle as long as I did my part. MTG
