Hello, I know everyone says to bed but let me explain first.... I have a custom build- Stiller, Timney, AICS, Bartlein barrel, SF brake. When I bought the AICS I was told by AI that the stock was "V block bedded" and didn't need anything. Just bolt it in and go. I have been having group problems with fliers and no matter who shoots it, it does the same. With all loads... Is there anyway that a rifle groups in particular that is indicative of a rifle that needs bedding??? Thanks for your time.
