Home Forums Hunting & Shooting Custom Rifles & Wildcats My new 6mmBR

Hard to top a 6mmBR. One of my favorites too!

I know what you mean about the streamline stock. I REALLY wish someone would make a detachable magazine that would be flush with the stock (using some non-paddle DBM like seekins). Being a 2-3 round mag wouldn't bother me a bit. I seldom shoot more than once in the woods but like having an extra round if needed. Single shots are no problem but having somewhere to keep an extra round near the gun becomes a pain.

I assume you are using the 223 AI mags with oppened feed lips? I am interested in building one that would accept the AI mags. I have seen several guys on sniperhides that are running them with success. Also a few guys using modified 308 mags.

Tanner, I am running a 6BRX along with several other 6BR's. I actually rebarreled to one after burning through a straight BR barrel in 10 twist. Not much more trouble other than the initial fireform. However, I'm only getting ~85+/- fps faster velocity with 2.2gr more powder. That does gets me just above 3000fps with a 105 bullet in 26" barrel! Although my latest build, I went back to straight 6BR (being a shorter barrel helped with that decision also).

Cool! A Dasher is something I would love to mess around with.

I have seen a number of HS precision magazines modified for the 6br. Those that have modified them have stated that they got perfect feeding with them.

I run a modified .308 AICS mag. It has an aluminum spacer in the front.

WHOA......THAT'S NICE!! I never had a Manners stock looks like I'll have to try one, any idea on how much the stock weighs Guy?

Around 27 ounces

Good deal enjoy your rifle Sir!

Darren have you looked into the new Wyatts 6BR magazine?

I have looked at them. Read coleridges post above. He has one, and the results are less than stellar. IIRC, his will only hold one down before it starts popping rounds out. Too much spring force

Hmm!

Yep, I have [bleep] with that box way too much & still not like it should be... Using a factory 223 Remington spring it will only hold one down, but it will feed that one like glass. I've tried shimming the box tight, loose, fixed, turned, bent, less bent, too bent; just about everything other than painting it (which I am assuming will effect feed as much as anything else I have tried ). I've been planning to cut down a AR-15 mag spring & try it but have been busy messing with other rifles since shooting season has arrived. I have been living with one round down.

My consensus is that the "Bryant" conversion is much better, cheaper & easier (once you get the spring placement correct).

I had a Model 7 done in 6 br, we decided to use a PTG bolt and we had them do a coned bolt. It has been feeding rounds perfect in the little use i have had with it in quick feeding situations. I am having a second barrel done in 284 at this time for it. The gun is a lightened 7, #1 Brux, a 16 z stock. We did nothing to the box and so far works good

Not sure if you seen my post on 6BR but...

Finally got time to mess with the Wyatts box again. I cut a spring from an AR-15 magazine I had laying around. Bent the spring & ears on follower so they would mate & "hooked" together quite well without any type of bonding. Then it was trial & error getting the correct spring length to get enough pressure but not too much (the 223 Rem spring would "pop" out the top round).

After some bending, twisting, & cussing I finally got the spring were it needed to be at correct length. My rifle I'm putting it in is a blind box mag so I closed in the bottom of the box as well to make things simple(pretty much made a magazine that sits under the action in the stock).

Bolted things up & it works like glass. The center feed really does work very well but for $50+ Wyatts should have things closer to "bolt up" than what this piece is. It is a good platform to get things started though. I bolted several rounds anyway I could trying to get it to "goof" & it always worked flawlessly.

Also, one thing I don't think I mentioned before... The lips of the magazine obviously sit just under the bolt. If you place a round over the lips (bolt open) it "floats" the round & acts as a follower. Unless a turtle is closing the bolt, the round slides right in the chamber . Works dang near as good as a single shot follower, really easy for loading just one round from the bench etc. I find this to be a real plus for the Wyatts as you can't do this with the Bryant conversion.

I still can only get two rounds down (they don't pop out, it's all the room that's in the box) but I feel that's plenty for hunting purposes. It really works well now. The center feed rails are perfect for the little BR case. Just be careful if you�re looking into this box. It is in NO WAY a drop in, but can be used to make a BR case feed extremely reliable.

Not sure if I would go the Wyatts box route again (mostly because of the added aggrevation) but it's sure working slick in the rifle now.

Thanks coleridge! I've been thinking of a 6 BR myself, but there's no place in my arsenal for a single shot bolt action. Really trying to decide whether I should do a 6 BR with the Wyatt's box, or just say "screw it" and go the easy route: 243 Ackley.

I would HIGHLY recomend the 6BR cartridge. It's my favorite for many reasons.

It really feeds better than what it has reputation for. Lot of guys feed them just fine out of an unmodified 700 bottom metal. Then it jsut doesn't work for some others...

My first repeater BR (standard BDL BM) wouldn't feed (reliable) until I did the Bryant conversion. After that, it would hold 3 in the belly & feed fine but it didn't like the 4th one (it tightened things too much). I lived with that through a barrel. WHen I rebarreled I went with a 6BRX. The mag was the same that it didn't like the 4th round in the belly (thought the slightly longer case would have helped). Carried it like that for a while then one day I got to messing with the spring, putting it in diff places on the floorplate. I finnally found the majic spot & things jsut "worked". I apoxy'd the spring in that spot & now it feeds all 4 like butter & havn't had a misfeed in over 2K rounds. If you put the rounds in correctly it is 100% dependable.

Do not be afraid of the 6BR for feeding reasons. It can be made to work. Some are easier than others. Anybody that can assymble a kids toy can make it work.

Thanks for the info. I've made 223 AI's feed like glass in 700's, which is sometimes easy and other times a bit more work, but I didn't consider any of them "difficult".

It's always hard reading someone's description of mechanical problems on the internet and knowing how tough it actually is; some folks are just not mechanically inclined and would call in a contractor to install a door knob.

I appreciate your description! I think I will do a 6 BR. I'll make it work.
