I know a gunsmith who worked on a Tikka that was destroyed by over pressure loads. These were worked up by a supposed commercial expert who then handed the ammo and formular to an unsusspecting customer. The bolt lugs had been driven back into the reciever causing cronic headspace problems. The reciever had stress cracks and had to be junked. Would this had been an issue in another brand of firearm I don't know. I know another shooter who had the same issue to a lesser extent when a hot batch of ADI AR2209 caught him out. There was a lot of machining involved to fix things up this rifle was also a Tikka.
