Very Poor Ejection - VIDEO ADDED

[Ganderite]

I took 7 guns to the range yesterday to test them with wax slugs.

6 of the guns worked perfectly. Even the semi-auto. But this Dominion (Turkish) pump would not eject the empties.

It extracted them just fine, but they fell back into the action, or stove piped. 7 out of 10 did not eject.

I don't know if this is a unique action or a clone of something.

It has a stud that should hit the rim and flick out the empty.

If I extract an empty slowly, the spring tension on the extractor flicks the empty a bit.

Any idea what the issue is?

Other than the ejection issue, i like the gun. It has screw in chokes, so I can use a full choke for knocking over steel in 3 gun.

How does it eject other brands of shells. I have seen certain brands of shells , usually cheap shells not eject properly. Sounds like your shells are working fine in other guns. Or the ejector could be screwed.

Just looking at those photos you presented Ganderite, could it be something as simple as the extractor spring
being a bit hefty?
Opposing the flick of the ejector button?

Good point. I will step out the back door and try some other brands.

The ammo that did not eject is Champion. Cheap, but has worked 100% in other guns.

edit: Tried other brands. Same problem. Looks like the extractor is tipping the case so it does not hit the stud.

I was wondering the same thing, but never dealt with this issue before, so have no idea what to expect.

I will play with some of the other guns and see if the extractor flicks the case, or just pulls it back to ejector stud.

Edit: The spring on the ejector of the other guns is similar in strength. I am wondering if the depth of the extractor could be an issue?

The other guns keep the shell captive until it hits the ejector stud.

Not familiar with that model. But, based on your description, it sounds as though the extractor is not making positive contact. The images appear to show an extractor only on the ejection port side of the action (as opposed to one on each side). This means that the extractor, if it's worn, doesn't get any help from an extractor on the other side of the shell. When you say that the shell sometimes falls back into the chamber, it leads me to think that the extractor isn't making positive contact. If this is the case, sometimes it will release the shell almost immediately and other times it will pull the shell out, but lose contact before having pulled the shell all the way back to the ejection stud.

This could be due to wear and/or damage to the contact edge on the extractor, or it could be due to failure of the spring that puts pressure on the extractor to maintain positive contact. In rare cases, this is due to dirt, oil, and crap gumming up the spring. Or, the spring could be broken.

Check the extractor for wear and inspect the spring assembly.

The ejector looks perfect. Spring tension is quite strong.

I was thinking the opposite. Too much tension.

 

[straightshooter]

Too much tension would not cause the extractor to release the shell early (which is why the shells sometimes fall back into the chamber). Also, too much spring tension wouldn't cause the fail-to-eject when the shell slams into the ejection stud. Both of the symptoms you describe are a result of the extractor not maintaining contact all the way past the ejection stud.

If the spring is good, the extractor must be bad; either worn or damaged.

The ejector does nothing other than stopping the shell cold on the inside while the extractor continues to pull the port side past the same point. The inside stopping dead while the port side of the shell is still being pulled back is what flings the shell out the port side.

First thing I would do would be a good cleaning of the chamber/ barrel and trying some factory shells not waxed as a starting point

It looks to me as if the extractor pusher/spring is not moving freely in the bolt, so the extractor will not maintain grip on the hull. Looks like crud and rust around it.

Yeah, I know that extractor pusher is probably not the right term for the part, but it should be pretty obvious.

Believe the word your looking for is extractor plunger.

No harm in pulling the extractor out and cleaning the spring and plunger . Easy to do , check YouTube

 

[Ganderite]

I saw what appears to be grease on the extractor plunger. I squirted some GP6 in there and flexed the extractor many times. It moves freely, but feels a bit gritty. It has a full arc of movement and has good tension, but not as much as my old Savage pump.

 

[madtrapper143]

Looks similar to an 870 extractor set up. I found that when our police guns started to do what you describe (and a new extractor was not readily available) I would "cut" the extractor so it sat deeper in the bolt and offered more "holding" tension on the cartridge. Generally fixed the gun for long term. see pic. If your extractor is configured like the one pictured try removing a very little amount and re install and check for improved tensioning. The 870 has a spring assist ejector but the gun you have does not. Increased tension will likely allow a harder pivot and more centrifugal force to aid ejection. Be sure to remove just what you need to. Make sure the extractor still enters the extractor cut and not the chamber.

Thanks. I will ask Canada Ammo for another spring and extractor. If they don't solve the problem, I will try some minor surgery.

Why spend any money until you clean it and try other ammo??
May be nothing wrong with it
Cheers

 

[Ganderite]

The gun is clean, and I cleaned the extractor.

And I tried different ammo (Rem, Win & CIL)

 

[REM3200]

Your bypassing the advice you asked for so question being why ask then ignore the advice?

Your problem is in the extractor.
- Remove and clean it and hole it seats in. Reinstall and try. If still fails refer to madtrappers advice.

Eliminate the possibilities prior to spending hours looking for and ordering parts then waiting an extended time to get them.

I took extractor out and plunger out and cleaned the channel. It now feels a bit smoother - less gritty. Tension on extractor hook is 6.5 lbs.

But is still does not flick the case out:

A seven year old will pump with more force than you do.
Pump the dam thing for god sake and not laying back sideways on your belly so one can see just how it cycles them
Cheers

 

[gunsaholic]

Agreed. Don't know if you actually pumped it harder than that when actually shooting it but in the video you aren't pumping it with near enough force.
