I think you're the first I ever have heard doing that. Cooper sounds like a good company.
To give everyone a better idea of how things happened,I will give a short summary.I was speaking with Clay and mentioned that the gun was shooting some great groups,but it was throwing the odd flier every few groups,with all loads that I tested.He contacted the tech guy at Cooper,who then called me to discuss the problem.He made suggestions as to things to try to eliminate the fliers,but nothing changed.We talked again,and then he suggested that I send the gun back for warranty work.I sent the gun to Clay,who handled everything from that point on.He did ask me if I wanted to wait until after hunting season,since with the border issues,the gun might not be back in time for our season opener.I decided to send the gun and take my chances with it getting back in time.The gun was delayed,and Clay lent me a brand new Excalibur in 280AI to hunt with until my gun arrived.When I commented on the accuracy of the rifle,he offered to sell it to me at a great deal,which I accepted.My Jackson Hunter arrived just as our season ended,so it will sit until next spring.
At no time did anyone suggest that my shooting or my loads were the reason for the accuracy issues.I did forward some of the initial groups to Clay and it was accepted that the gun was at fault.Both Clay and Cooper displayed first class customer service in dealing with the issue.
I will mention,that even with the fliers,the groups that I was shooting would still meet any Weatherby,Tikka,or Sako accuracy guarantee,but Cooper offers an even better guarantee than those companies,and the gun would not consistently meet the Cooper standard of three shots in 1/2" at 100 yards.
