You guys are arguing about a problem that NEf addressed with the mechanical extractor. What you are seeing is a difference between how the ejectors on different guns, manufactured at different times, are sprung. Originally, NEF was making the ejector with a single spring, but it would not always lift up to catch the rim groove of a rimless cartridge. I have seen examples of these of that the case drug on the ejector and others that the ejector was 1/16" to 1/8" below the case on closing. The real question is does the case eject? In an attempt to fix ejectors that did not do the job, NEF began to put in two springs, then changed to a stronger single spring, but this was no always effective. The real solution was the mechanical extractor that NEF fitting barrels with this year.
SO, you will find extractors that don't touch the case before closing and ejectors that do touch the case before closing. Again the question is does it eject? If so, there is no defect, as the defect is the ejection or lack of, not when the ejector slips into the groove of a rimless cartridge.
On a rimmed cartridge, the ejector simply moves forward and aft. the Ejector on a rimless cartridge has a different action and will also move up and down so that it will catch the groove. If it didn't, it either wouldn't catche the groove, or it wouldn't allow a cartridge to be inserted into the chamber.
NEF seems to have addresed most of this problem, now if we could just get them to use better barrels.
