I have been messing about with my new modell 700 LSS in .280, and first 2-3 shots are always good, then it starts shooting all over the target.
I'm shooting 160 gr, Fed Premium Nosler AcuBonds.
Checking it over, the barrel is touching right over the raised rib where the front post is mounted. Could it be as easy as the barrel heating up and throwing my shots? I had my Tikka 7mmRM right there to compare, and it is spot on as per usual.
I was going to sand the section down to allow a dollar bill to be passed under the barrel.
