The problem lies with the manufacturers refusing to believe they turn out crap. Remington for example thier acceptance for hunting rifles is 2":-

Industry standard is 2 inches or less for hunting rifles. Proper ammunition and optics should make this very easy.

Note how they claim this is the industry standard! Sako however say 1 MOA is their aceptance level:-

Dear Mr Peckham,

Thank you for your email and for your interest towards SAKO products. Each and every rifle that leaves Sako factory is test shot for accuracy and the minimum requirement is 1MOA, using our own, high quality ammunition. At the moment we do not supply the rifles with test targets.

I wish you the best of luck in your search for a new rifle and hope you will end up choosing a Sako or a Tikka.

Best regards,

Parker-Hale claimed that their rifles would produce groups of 1 1/2" or less using fresh Norma factory ammunition.

Yet they tell us how superior modern manufacturing processes are yet what they really mean is that it's superior for profits and nothing else. If anything quality has dropped not improved.

Weatherby well I have never been impressed with them and worked out long ago that Roy was a liar plain and simple a con man and a good one at that. This reminds me of Stans super dooper 30-378 MkV that you cold not hit a bar door with. Groups were a foot plus so it went back and Weatherby tweaked it and sent it back and it was no better so back it went again this went on for over a year and eventually after Weatherby had replaced so much that only the bolt and trigger were the originals Stans brother Steve took it to his gunsmith who stripped it and rebuilt it with some more new bits and blueprinted it and finally it was able to shoot properly. That was back in 2005 or thereabouts.
