Call Vudoo. You may be able to send it in and they can "touch" up the chamber. Exchange the extractor or maybe even a new barrel.
Bartlein commented on that video:
”
A lighter weight contour when the barrel gets button rifled (Bartlein Barrels only does single point cut rifling) the stress being put into the blank is much greater. As you turn the contour smaller and smaller in size this can have a negative effect on the bore sizes changing and opening up. When this happens you cannot make the bore size smaller. This is not an issue with single point cut rifling. We don’t see this happening at all. Same can be said about threading the muzzle of the barrel for a muzzle brake or suppressor attachment. On button rifled barrels, threading the muzzle this is a common problem with the bore opening up. The last place you want the bore to open up or go sour on you is right at the muzzle's crown edge. Anything going wrong here has a negative impact on accuracy.
The video link below shows this process happening. The point of the video isn’t to pick on other barrel makers but to suggest to people to make the muzzle threads as large as you can to prevent this from happening. The first barrels where all the bores open up are all button rifled barrels. The last barrels are Bartlein cut rifled barrels. Yes the threads are larger on our barrels but we have made barrels with muzzle threads that measured 5/8” and we turned these down from a blank that started out at 2.280” o.d. and have not scrapped/rejected a single barrel because of it.”

Never got those barrels. The part about the barrel expanding when the outside diameter is reduced is absolutely true. But the cure is simple.
This Eley problem is interesting as I have a 360 repeater that feeds and extracts Eley 10x with no problems. This problem should not exist if Vudoo only uses one chamber in their repeaters and their tolerences held to very high standards as they claim! My 360 will also extract a live Eley round which tells me the bullet is not engaging the rifleing very much. Not being able to shoot Eley is something I would not tolerate as Eley still produces some of the most accurate ammo made.Sounds like the solution for everyone is...
Don't shoot Eley in a Vudoo!
Congrats!
. I’m going to have a shoot off with my cz457 with a lilja barrel that shoots lights out with center x at 50yds. Hoping this vudoo makes me smile as much as my cz457 does. Single hole 5 round groups or bust. If my cz can do it, surely a vudoo can. 20” mtu barrel. Can’t wait to throw my can on it and seeing what she can do at 100. My cz has been on steel at 400, although it was probably 12”x24”, still cool to hear the ping of the steel at that distance. Haven’t been able to hit at 500 but hoping my new lady can make it happen.
Who would be the 2 manufactures of said rimfire tuners you've talked to? First I have nothing to say about Mike's product other than you don't see them on winning guns on the national level. The most popular tuners on the market as of today would be harrell and the pqp and they both do the same thing. There is no magic dust that helps reduce vibrations look at winning guns that's all one needs to do. The top of the top don't use magic tuners and rarely if at all move their tuners once tune is astablished.
Not lost but trying to figure how a rimfire will not be effected by the harmonics of the load as centerfire rounds are. So you lot test ammo after tuning the rifle to a certain ammo so you are finding ammo that is compatible to that tune on the barrel. Basically doing it a different way in tuning rifle first and then finding ammo that will work with that tune versus shooting the ammo and tuning to the rifle to the ammo. And not saying turn crap ammo into winning ammo but there has to be something in the ammo that is good to begin with that would make it fall into that barrels tune you already set.
I have the J&L tuner from Joe Chacon and he says exactly the same as you about tuning the barrel and not the ammo.

Mine is tuned to the 9th harmonic by Joe and has never been touched by me either.
My barrel with Joe's tuner has put several different brands of ammo into a ragged one-hole group on numerous occasions.
Custom remfire builders slug their barrel blanks to determine where the tight spots are. This is where they cut and place the crown. Their not concerned with the 9 harmonic. Taper lapping is also used to produce the same results.
Well. if you don't like the 9th you can always use the 7th or the 5th or the 11th or whatever. Never made much sense to me!
