6 br / Dasher brass ejection question.

[Phil]

I`ve never tried this before, so i have to ask.....

Will a .473 bolt Remington eject the 6 br / Dasher case with the factory ejector / extractor?????

Single shot action, so i don`t care about the feeding aspects.

my ejector spring was strong enough it would cause dented case necks on my dasher brass, I took a coil off and it's fine now. if I run the bolt very slowly the brass sometimes does not eject but flips around in the action. you have to make it do it tho.

I don`t have a problem trimming an ejector spring, especially if that is the biggest problem i`ll encounter.

Thanks to all for the confirmation.

My original post i said ejector, i have since modified it to include the extractor, as this is what i meant to say in the first place.......

It wouldn't change any of the answers. 6 BR and Dasher are the same case head as all .308 based cases and the Remington .473 bolt face accommodates them all. Use of a shorter or softer ejector spring does help and is popular even with longer cases as it reduces the tendency to ding the necks of the case and keeps then from flying off into the woods.

I think what he is asking is because a lot of actions won't eject a BR or Dasher case. Remington's seem to work, as do most customs with a static or sako type. The slide type extractors don't work well. Matt

That is true, and it is because with the sliding plate extractor in the bolt lug, it tends to push the front of the case into the bolt lug raceway and the shorter case may pop out of the bolt face prematurely. The Remington and other extractors that angle the ejection higher are less likely to encounter this.

Thanks guy`s.......

I`m excited about building this rifle.....

My factory s/a rem 700 would not eject a 6br to save its life. 1 maybe 2 out of 10.

I fitted it with a PTG bolt and a mini M16 extractor and trimmed the ejector spring.

 

[Alex Wheeler]

It might. I have made them work by modifying the plunger to come out a little more to keep pressure on the case longer. The whole problem is a short case can swing out into the lug race way and unload the ejector. With the ejector unloaded there is nothing keeping the case drop dropping of the extractor and staying in the action. If you need it 100% no matter how you cycle the bolt you will probably end up with a sako or mini 16 or maybe one of the Borden internal hook extractors when he offers them to gunsmiths.

After looking at a number of bolts from older and newer rifles, I noticed that the protrusion of the ejector varies noticeably and some are slightly radiused on the end. I don't know if this is intentional, but it certainly is important for short cases. Maybe I just got lucky on the few I did with factory bolts.

This is a good read. Josh is a accomplished smith. http://www.scout.com/military/snipe...6br-6dasher-testing-for-function-in-an-action

Some are reporting slight mods needed for extraction with the Norma Dasher brass, my action did not need it. but I do know the rim is thicker as my shellholder needed changed out. also if you are thinking repeater check out the Aics mag kit by Primal Arms.

I have had the very best luck with an M16 extractor. Sometimes a Sako extractor will work, sometimes not. The M16 extractor seems to have the best combination of grip angle and spring tension. At least on my personal rifles so far. Good luck.

Idahoorion,

It`s a single shot action, but thanks for the link, it is a good read.

Paul,

I`ve been talking with Alex about doing the M-16 extractor.....

Thanks for all the help, first hand experience can`t be beat......

Phil.

The stock extractor in a Remington bolt is a "C" shaped piece that rides in a groove in the bolt head. Some of them had a small rivet that you had to peen in to hold it in place. They work fine, but a lot of folks, especially when building up an action with new barrel, etc, will go with the Sako or similar extractor that has a little more "beef" to it. Nothing wrong with the stock extractor for 6BR or Dasher, they should be easy to extract as they are pretty low pressure....However, any time the bolt lifts, but does not want to extract the spent case, use a brass rod, or cleaning rod to encourage the brass to eject. If the stock ejector slips off a couple of times, sometimes they will bend and that is not a good thing. For my silhouette shooting in real warm weather, I always had a cleaning rod or brass rod available right there to encourage any sticky brass due to higher pressures on super hot days.

Hope this helps some more....

The issue is not that the extractor wont extract the case, its the angle it does it at the causes the short cases to fall off the extractor and drop back into the action. And I certainly wouldnt say the br or dasher is low pressure. Most guys run them at 65k and up.

My 700 will not eject the br case 4 out of 5 times. The same action and bolt will kick out 99% of the brx cases. The ejector and extractor are unmodified.

 

[Pulpit]

Just shot a few groups with my factory Rem 700 action with Remage setup in 6br.

Mine doesn't eject very well. 9/10 or so get loose in the action on top of the next round (it's a repeater).

Do I need to send my bolt or entire action/rifle to get this fixed as I'd like 100% the cases to eject as I'm used to with the longer cartridges.

Any suggestions? Thanks.
