Plugging Ejector Hole

[Old Navy]

Is there any advantage to be had plugging the ejector hole? Later! Frank

Can't imagine any real advantage of any kind.

No more ejector marks from hot loads = more uniform seating depths and a flat square surface for the round to abutt the bolt face.

Why not cut a coil or two off the ejector spring so that you can push the ejector flush by hand? That way you still have ejection function, better brass handling, and ejector won't leave mark.

I think the ejector will leave a mark unless it is plugged with a non-moving solid plug. If the ejector has some of the spring tension taken off so it is flush with the bolt face it will still leave marks. The marks left by ejectors is not left by the ejector but by the ability of the brass to slightly flow into the hole becasue it is not solid.

 

[jlow]

Wwbrown is correct; the mark is not left by the ejector but by the brass flowing around the ejector because the load is too hot. But sernousely, ejector marks are a safety sign for you to tell the load is too hot, you really want to prevent that from happening?

 

[Webster]

Correct as someone responded. The shiny mark cannot be caused by just the tip of the ejector because the shiny mark from a hot load is at least five times the diameter of the ejector pin or pin hole. In other words the shiny mark is around the ejector pin not at the pin. If you see shiny marks on the case head the loads are to hot for you rifle. Pushing straight back on the case head shouldn't cause the shiny mark. If you back off the marks disappear. The ejector should not interfere with head space or prevent the case head from being flush with the bolt. The bolt closing ramp and bolt arm leverage exert plenty of force to push against the ejection spring. I want to see signs of high pressure when I am working up loads. I don't want to do things hide evidence of pressure. When working up loads I look for three signs of pressure.
1. Flattened primer rim.
2. Shiny mark on case head face.
3. More effort to lift the bolt.
4. Stay below published max loads.
I have read articles recently by experts. They say you can have high pressure without flattened primers. That is what I see with my 6BR. When I get about 1/3 to 1/2 grain too much I see a shiny spot on the case head, increased bolt lift resistance and normal looking primers. I have never measured case head expansion with a micrometer for evidence of pressure.

No more ejector marks from hot loads = more uniform seating depths and a flat square surface for the round to abutt the bolt face.

These are the advantages. I had Gre-Tan plug my ejector hole, bushed and sleeved the firing pin hole and refaced the bolt. Caseheads look perfect regardless of pressure.

Not having an ejector is no issue for F-Class, speed-wise. Not ejecting allows you to take better care of that brass you worked so hard on.

Works for me anyway.

 

[Webster]

Does it shoot any better?

I just got a new action w/o ejector and in the process of building it. I will let you know. At least I can measure off a flat base and seat off a flat base more accurately. That will be good for peace of mine if nothing else.

You have a point on losing an over pressure sign. I figured I'd just go on flat primers, sticky bolt, blow back around the primer.
