Need help diagnosing FTE issues

[Old Bob]

Could be your extractor. Check to see if its "ears" have sharp points. Are there "fang" marks on the inside of the cartridge rims? If your extractor does have points & leaves fang marks, you'll probably have to grind off the points until you get good ejection at every shot. With your bolt removed from the carrier, you can check this by placing a cartridge under the extractor & then pushing it from the side like the ejector plunger would be pushing it out of the bolt. If the cartridge sticks in the bolt, the extractor will need modification. There are YouTube videos on this plus recent threads in this forum discussing the problem.
