I put a Crieterium remage 280 AI barrel on a Remington 700 long action and put in a greyboe stock. While I have not done much load development I have shot about 100 rounds through the barrel. Set up my long distance camera and shot for a group at 500 yards. Thing grouped like a shotgun, about 24 to 30 inches. Trying to decide where to go next. I'm not confident I'll be able to get the thing to do what I want which is repeatable 7 inch groups at 500 yards. Does anyone think I'll be able to get this thing to shoot with load development or should I send the barrel back and see what the vendor will do for me. Thanks for your opinions.
