I recently had some frustration with a .280 ai build. I had built a 280 ai for myself and my long time hunting partner and friend wanted one as well. We put one together for him using basically al the same components just in a different color. Mine shoots well and still does but his was never consistent. The same smith and reamer was used as well as the same loads initially. The rifle would print good one day then be way off the next while mine was always consistent. After believing I just had the figure out the right combination for way to long we scrapped it and redid the barrel. We turned it into a 7mag with a new barrel and opened up bolt face and now it shoots great with Berger 168's. I recently sent in the barrel and they said it had a scratch near the muzzle but they could not prove it. The company also said that there is no way it could have been that way from the start. I'm super frustrated and borderline never want to use their barrels again. I tried to explain that all the others barrels that I have of theirs are treated the same cleaned the same and shoot well but this one just never seemed to print. I'm basically SOL and eating the cost of a re barrel for a rifle that we never were able to use. Has this ever happened to someone?
