Answer I'm not an expert on I.J. 's, I'm here looking for answers myself, but to my knowledge, older doubles and o/u's didn't have ejectors unless it was a reputable name brand and would be a more expencive model. I can't prove it true, but this what I was told by a few local old timers, they have more experience then me, I don't have much choice too believe it until found wrong.
Fit the firing pin stop you are ready to tune your extractor. Rides up the breechface under the extractor. Sharp edges as shown in figure 1.
Stock extractor on the bottom. Groove on the extractor. Belly of the extractor.
If the edge of the hook rides in the extractor groove. At this point, you need to adjust the extractor tension. Work to push the round under the extractor.
From feeding up the breechface. Then check that the round slides under the extractor smoothly. Go a little at a time until it you get it right.
Another option is to install an Aftec extractor. Of bending the extractor, the Aftec has a set of springs that provide tension. There are a couple of tricks to fitting an Aftec.
Edges because they have already been beveled. Slightly on the firing pin stop. Longer the ejector the sooner the round will eject.
This is a good thing. Ejector can be shaped to affect the angle at which the round leaves the gun. The higher the impact point, the lower the ejection path.
Ejector from the top and the bottom at about a 10-degree angle. Blunt point on the extractor with an almost flat face. The ejector at only one point, this produces a more consistent ejection pattern.
Hitting the port and coming out high. Lower in this case you will exacerbate the problem.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
