GUESTHUNTER,
Your story about your Ruger sounds exactly like the problems a friend of mine hade with his Browning 525 skeet.
He finally solved the problem by shooting only reloads, and not sizing the brass. The chamber was cut too deep in the area of the rim, and factory shells as well as reloads that were sized dropped too far into the chamber where the fireing pin could not make proper contact.
