Mr Apperson; thanks for your advice. Both grooves on the action look the same and have no dirt nor debris inside either groove. The trip ends of the ejector sears both look the same. with no wear and not bent, etc. More information, I went to the range and shot again. The left barrel ejector hammer cocks and works just fine when the gun is dry fired without shells. Its timing seems perfect. But when firing one shell in the left barrel, no shell in the right, the left ejector hammer does not eject at all. It acts like an extractor. Seems like its jarring off when the gun is fired. Looking at the bottom of the "L" on the left ejector sear, the leg of the L is bent upward toward the barrels very slightly. It's not at exactly 90 degrees. Next I took the wood off the fore end metal and put the bare piece on the gun to see whats up. The top of the left sear seems to move nicely into the knotch on the hammer when the barrel is dry fired. It doesn't look like a tiny hair trigger engagement. But that only simulates the dry fire setup. Any other ideas from this informatoin would be greatly would be appreciated.
