About ten years ago, Rick Jameson in Shooting Times got his first Oehler M43 and tested some of his own maximum loads in the .22-250. He found that even though the loads looked fine in his rifles, he recorded pressures in excess of 80,000 psi! Tough cases and primers can be deceptive indicators of pressure......and a ruptured case at 80,000 psi is FAR more dangerous than one at 60,000 psi. ;)
