6BR Repeater Project-Feeding Update

[oklahomaboy]

I have read and re-read Mike Bryant's Page regarding his fix for feeding a 6BR in a Remington action. It seems to be a straight-forward, easy fix. But for those who have tried it, how effective is this modification? I'm planning such a build for use as a hunting gun for coyote and an occasional deer using a blind ADL magazine but if this is not a sure-fire cure for feeding problems, I will consider a 6x47 Lapua or a 243 Win. I will likely use the 80gr. Berger for coyotes and a 85gr. Nosler Partition or 90gr. Ballistic Tip for Deer. This would allow me to use a 10 twist barrel.

If you have related knowledge that you can share, please let me hear from you!

Walt.

I have not read Mike page. But I had a 6BRBS (6BR IMP) on a remington. All that was done was to extend the slot on ejector plunger to let it come out farther and keep pressure on the case until it can eject. That was for ejecting only mine was a single shot action

Re: 6BR Repeater Project-Tell me about Feeding!

I tried it and it did not work at all. The front of the cartridge kept pointing up causing the rear to go down to where the bolt would ride across the top and would not push it forward. It was useless. Im back to factory setup, as long as I keep the cartridges forward in the mag box it feeds good as long as I take my time. Had a couple jams when I try to reload quicky. Im sure a 6x47L of 6xc would feed much better.

Re: 6BR Repeater Project-Tell me about Feeding!

As long as the Remmy in in one Gary Eliseo's tube guns with BR mags it works great. If not then I would look to a longer case. Just my 0.02.

Re: 6BR Repeater Project-Tell me about Feeding!

Thanks so much. This is the type of feedback I'm interested in. Please continue to reply if you have insight into this modification. I plan on using a McMillan stock for hunting so a tube gun is definately not in the plans.

Re: 6BR Repeater Project-Tell me about Feeding!

I have no 6BR experience but boy am I happy with my 6x47 Lapua as a hunting round. It seems to shoot every weight bullet to virtually the same point of impact so far and I had no trouble dispatching several antelope last fall. I now have a non-lead load for hunting here where normal bullets have been outlawed to save the condors. Tom

Re: 6BR Repeater Project-Tell me about Feeding!

Ya know.....this has been an issue with me for a little while. I have had a 6BR and now a 20BR as repeaters for coyote hunting. I did basically Mike Bryants fix for both, and sure it will feed but you have to get a feel for it... or...sure enough.....the tip goes high and the base goes low, and Jammo!!!

So, as you figured out there is more to skinning this cat, or maybe I just need to have a real gunsmith look at it.

But IMO, the other big part of the equation has to do with the feed lips. At least in a Rem 700 action, they are too wide or too narrow (not looking at it right now, and can't remember which) for the BR case. I am thinking of another build in 20BR (such a great coyote slayer ;D)...So, my thoughts are that maybe the good folks at BAT can shed some light on the subject, as I see they have a repeating action that they list for a .22BR/6BR. I am planning on making a call to them and I will post the information that I get.


Hey, or maybe someone has succeeded using a detachable box Mag.......center feed or something. :-\

Re: 6BR Repeater Project-Tell me about Feeding!

I've got a Remington 700 in 6BRX that I did the mag box mods mentioned above. Mine feeds pretty darn well. You do have to pay attention when putting rounds in the mag, but as long as you do that, it works fine.

Re: 6BR Repeater Project-Tell me about Feeding!

I've built several Dashers on M700s & one M70 Win. pushfeed. Since I've had very little luck in getting mine to eject reliably, I converted them to single shots. Odd thing is, the Dasher I built on a 700 for a customer never failed to eject reliably, and since he's got H-S Precision DM bottom metal, he doesn't have any feeding issues either.

I've also done a few Eliseo R5 tubeguns (including one with a Pearce TG action for myself). Feeding is a non-issue with Gary's magazines, but ejection is still somewhat weak, and that's with a PTG bolt that has a Sako-type extractor. I have to cycle the bolt on my R5 rather briskly to get reliable ejection during rapidfire strings.

OTOH, a 6x47L repeater I built for myself is 100% reliable with mag-fed rounds. It was originally a 308, and no mods were necessary to get it to work with the Lapua round. Same goes for a Howa 1500 short action in 6XC - it's one of the slickest-running bolt rifles I've seen. Ejection with these two rounds is at least as positive as with a 243 or 308. Much as I love the BR & Dasher, if I were building a hunting or tactical rifle, I'd probably go with the longer case of the 6x47 or 6XC, strictly from the reliability side of things.

 

[oklahomaboy]

First, thanks for all your replies as I value each of them. Now, an update on the 6BR Repeater Project: Today, I took a 6BR 700 action with a heavier barrel than my planned project and inlet the barrel and action into a stock that originally accommodated a 22-250 I recently sold. I took a 308 ADL mag box along with a shortened 308 follower, glued in a .223 mag. spacer (didn't want to cut up the mag box just yet)generally following the Mike Bryant directions for a BR repeater. I took three cartridges and loaded the magazine and worked the bolt. Wow, it fed slicker than snot on a gun barrel!!! That's not to say I can't get it to jam but the results went a long way in restoring my confidence in my planned project. I can't think of a better 300-400 yard coyote rifle than a 6BR sporter repeater if it is reliable. More testing to come once I get the stock bedded.

I also tried Mike Bryant's mag conversion but it didn't completely solve all the problems. I believe the ejection problems mostly cause by the shortness of case allowing the case neck to strike the top of the action prior to being ejected out the port. I actually was getting a small dings on the end of the case neck opening and ended up removing the ejector to eliminate case neck damage. Being my rifle was being used for shooting p-dogs making it a single shot wasn't a issue. Sometimes it would strike the top of the action knocking the case free of the extractor. You can see how this would lead to a jamming.

[Fordnutter]

As per Bryant Custom conversion details did the same thing on my Remington Model 7.
Did it feed....barely yes....but after spending a small fortune for the best of everything
passable is not good enough. I got so hacked off with the sloppyness & lack of
consistency I binned the parts & glued a single shot follower in place.
Now feeds like a dream, no damaged cases (they are expensive in my part of the world)
& a little lighter wallet.

 

[DCRYDER]

Im glad that you had better luck than I did, and since other people are having decent luck at it I MAY try it again sometime when im really really bored. But if worse comes to worse you can do what I had to do with my old 22BR (which fed much worse than my 6BR) stick a single shot follower in it and make a 2 shot repeater. Twice as good as a single shot!!! And it worked.

 

[oklahomaboy]

I don't know if there is a trick to Bryant's method, but I seem to have learned that the upper and lower portions of the spring need to be parallel (my old one bends sort of easy and may need replacement) and of course use the 223 spring with the cast and shortened 308 follower. The location of the spring on the follower seems to matter in that in apparently needs to be centered. I'll have to epoxy mine in place. If it gets toward the rear of the follower, the nose of the follow will dip into the mag box. Not sure it matters, but have you noticed there are two (perhaps more) 308 followers around-the newest one and the one I used has a steep ridge that fits against the left side of the box. Earlier ones have a less prominent ridge. I also called BAT machine about their 6BR cartridge classification of their varmint repeater and they indicate their is nothing specific about that action for the BR and any problems associated with feeding a BR case into a 700 would also apply to their action as well. More to come as I work toward my goal.

 

[JLDavid]

I have a 22BRX and a 6BRX in 700s and your follower spring location is definetly important. You are right on with epoxying it in the center. I did the same thing and I have not had any problems since. Both of my followers have the steep ridge and hold the last case very well. Don't give up, it works well when all the little things are addressed. Good luck.

 

[Ackman]

A friend's 20BR feeds well through the Savage action as is. If the 20BR does, a 6BR should also feed well.

 

[RonRouse]

Ackman, does your friend's Savage rifle use a center-feed magazine? If so, that's probably the reason it works so well with the BR case. Interesting.

 

[queen_stick]

I'm putting together a 6mm Dasher right now for varmints. I was going to use a single shot follower, but changed my mind since I had the mag parts that came with the action.

It's built on an OLD Savage model 10 action (It's the old ""short action" that's actually a 'medium' action - it's between the newer model 10's (short) and the newer model 110's (long)). It's a blind mag setup, but then length of the "medium" action is awesome because there's plenty of length in the mag well for seating the long VLD's out to the lands.

Anyway, I only have one dummy round made up, so I jammed it down into the mag and tried feeding it out of the mag with the bolt. It worked repeatedly with no trouble at all, which I was surprised to see. Then I stuck an empty case in the mag first, then stuck the dummy round on top of that (simulating 2 rounds in the mag). It doesn't want to feed too well if there's more than one round in the mag. It would seriously work better if I stuck the rounds in the magazine backwards. (joking).

I haven't played with it too much, because I've been working on other parts of the rifle, but I definitely want to try to get this to work. If I figure out how to improve the feeding I'll post it here. Meanwhile, I'll continue to read everyone's responses and learn more about the subject.

 

[HammerDown]

Raising the dead on this old thread. I'm building a 6BR repeater using AI mags. Has anyone tried to modified the new .223 AI mags to work with the 6BR cartridge?

 

[RandyD]

I am also interested in what you try and what works and I'll post my results too. I made a walking varminter rifle out of a stiller action, which is a Remington 700 clone, it has a Krieger barrel in 6mmBR and it is bedded in a McMillan Hunters Edge stock with a blind magazine(ADL). I have not worked on the magazine yet, but I intend to start on it during the Christmas break, and will be ordering an extra magazine box, .223 spring and a 308 follower from Brownells tomorrow.
