BAT 3Lug weak ejector… help needed to run em fast on condition

[EEP]

I built a short range BR for score rifle a couple years ago on a BAT 3Lug action. The action cycle is smooth as silk and I love the 60deg throw. The rifle is very competitive but when I need to run it fast on a condition I often get held up with a piece of brass that didn’t eject or sometimes gets flipped around and I have to come off the gun and pick it out and get back going but often the target suffers from my inability or patience to wait on the right condition to return. I understand I can work on the latter and this is a known issue for the 3L’s but I haven’t found a great fix for the weak 3L ejector yet…. Does anyone have a sustainable solution for the weak 3Lug ejector, a stiffer spring, etc. without doing something too wonky? For those that are going to give me this response, I have reached out to BAT on this as well a couple times and once more recently with no response. Any help here would be greatly appreciated!

Usually the solution is as simple as a stronger ejector spring.
You did not say if this was a PPC bolt face, or a “generic” that will extract and eject either 6PPC or BR.

I have a Bat Neuvo that has the combination bolt face. I set it up to gently eject a 30BR case. When I screwed a 6PPC barrel on it, it would fail to eject about one out of four times.

I got a stiffer spring from Bullet Central and it cured the problem. It does flip the case out a little further than I want, but that’s better than it not ejecting at all.

I also have a Bat ds I shorten my ejection spring I to have a br bolt face a shoot ppc in it I can open my cartridge box the shot rounds go in the open lid 80% of the time ppc an 30 br

It has a PPC/BR bolt face. I have replaced the spring and plunger.

How did you specify a stronger spring when bought from BC or did you buy their standard replacement offering for the 3L? I see now it’s states upgrade spring and I’m not sure when I bought mine it said that.

If I shorten the spring won’t that make it weaker?

I would think so. The problem, as I have encountered on another brand, could be the extractor instead of the ejector. The extractor may be dropping the empty off the bolt before it should.

Well that just sucks.

I had that problem with my bat I called kelbys an got springs for the sako extractor replaced the spring no problem ever since

 

[David Conder]

Bat must have a bad shipment of springs when I called bat they told me it would take weeks to get me some springs so kelbys they shipped the same day at no
Cost. Top Company that why I just bought 2 pandas

Update.. I had a spare ejector spring and ejector pin and tried multiple variations of spring and pins with no improvement. BAT emailed me back describing exactly what I’m seeing and suggested replacing the extractor with an upgrade. It’s funny I thought too the extractor just wasn’t holding the case well enough. Got one on order and hope to get it by the end of the week and try it out. I’ll keep you guys posted on how it goes.

the same problem i had with my bat the extractor spring last spring back
Eep you are down in the eastern part of North Carolina ps is the case turning around in the chamber

Eastern NC…. Allot of times it turns around!

mine did the same thing I replace the spring that fixed it I had a longer spring had to keep cutting the spring off till I could get the extractor back in place

I replaced the extractor like BAT suggested, that alone did not help. New ejector and spring did not help. I tried shortening old spring several times and that didn’t work either.

What is working now on the bench at least is a combination of new extractor, an old ejector that I cut down to shorten it up and a new spring.

Maybe a different combination of something I had would’ve worked, who knows. It has been a finicky trial to get it right which is a little frustrating.

I have yet to try it out on the shooting bench for the final test, so hopefully i’ll give one more update that will be positive after the weekend.

Nobody wants to say it but you are not the first person to have problems with the combination BR/PPC bolt face.

As I said in my other post, ejecting the BR is no problem. But unless you get everything perfect, problems can crop up with PPC bolt face when cycling the bolt fast.

If you're shooting a PPC get a dedicated bolt

Sounds like someone trimmed the factory spring to the point its too short. What you need is a lighter spring rate that has the necessary travel.

I replaced mine from a brownells compression spring assortment. Went with a lighter spring rate that allows the travel to be reliable. Been working for 8 years now, haha. I can look at what assortment and spring I used if anyone is interested in the info.

I've had good luck by lengthening the ejector stroke a little bit. Just remove the ejector pin and lengthen the slot about .050 or so. It'll let the ejector hold against the case a little longer. The short cases "run away" from the ejector and when it runs out of stroke, it falls off of the extractor. Hope this helps. I've seen it quite a bit on those actions...fwiw.
Another way is shim the bolt face diameter to keep the case from coming out from under the extractor. I've had to do that too on a few, particularly the combo bolt face models.

I’m shooting 30BR, but thanks!

That sounds like exactly what it needs!
