ronlaughlin said:Continuing on with the research, this morning the breech plug was installed into the Omega using the torque driver, instead of the 1/4" ratchet. The plug had a drop of oil on the threads is all. NO tape, or anti-seize grease was used. The Driver was set to a torque of 30 inch pound, and the plug was tightened at that torque. Wanted to see how much torque it would take to remove the plug, and also, how far the blow by junk, would migrate through the threads. A high pressure load was desired; powder charge was 110g Blackhorn, and the bullet was 300g XTP.
The photo reveal the carbon made it near half way through the threads, so is this a middle seal plug?? When i went to remove the plug, the torque setting on the driver, was left the same as it was when the plug was installed. What i figured to do, was to gradually increase the torque setting, until the plug broke loose. Imagine my surprise, when the 30 inch pound torque broke the plug free, and it was removed from the rifle.
Oops, forgot to say that 11 shots were made.
Thank you Ron. This is good information...........
