short range 6BR?? redirected, a bit. read on!!

Here is a topic that may spark a little interest, maybe not?? Anyway, I have a nice BAT MB action sitting in my safe with no plans as to what i am going to do with the darn thing. The action has a 308 bolt face so i am a bit limited as to what i can do with it as far as a ppc goes. I was told it was a combo bolt but it will not pull a ppc case as i have already tried. Bat may be able to modify the extractor a bit, but I'm not sure. Anyway I have had several ideas cross my mind but nothing solid comes to mind yet. One of my ideas is to build a 22 or 6br on a short (.100-.150) case but i just dont know. I would have to have a lot of extra tools to do this, and those extra tools = money. So the latest idea is to build a straight 22 or 6BR and shooting 68gr bullets. I have always read that the 6BR will never compete with a 6ppc. Then i read Tony B's book and he made a comment along the lines of- the 6ppc is so accurate because of all the info and loading equipment that is dedicated to this chambering. It kinda sounded like maybe tony isn't 100% certain it is simply the case design? Now maybe i read this wrong, and i am taking all this out of content, but it has me thinking. So my question to al of you is, Do any of you think a straight 6BR with a 14 twist barrel can shoot with a 6ppc? Can a shortened .100 6br shoot with a 6ppc?
I can always build a long range rifle with this action or sell it or whatever, but i really like the action and i would like to build a short range tack driver with it. again fellas just another thing i have been thinking about, and I'm bored on this here rainy cold day. I have also been wanting a 30x47L for groundhog shoots, but the truth there is, I already have a great rifle i can use for this purpose. I dont need anything, i just like rifles!!!! LOL!! Lee

Absolutely, a good 6BR can shoot with a PPC all day long and some days it may even catch it but most days it will come up just a little short.
I started shooting BR with a 6BR in 1982 BTW.

PS a 25BR is even better when you can find good bullets

Need? What does Need have to do with it? oh and I have a 30x47 I shoot very successfully at Groundhog shoots.
 
I went so far as to order two consecutive "identical" barrels from Krieger, had them chambered in 6PPC and 6BR for the same rifle.

then switched 'em.........

Complete waste of energy. In my opinion it would take years and many barrels to find a difference, if there is one.

Here are two things I feel strongly about concerning 14 twist 6BR/6PPC;

-to get a BR to perform you MUST!!!!! short chamber it like a PPC. Slopping in a "min SAAMI" chamber on the BR is serving it short shrift. There is all sorts of misleading crap written concerning accuracy of 6BR wherein the author doesn't even consider this difference. I've argued passionately with folks who howl about "the caseheads are crooked on the 6BR!! It's TOO BIG and can't get flat!" OK, I'll stop now, nobody cares enough to test it anyway......

-don't expect any extra velocity from the BR

I don't know about your BAT, but my Viper, with a sliding plate extractor and a .308 bolt face works without a hitch with PPCs. How did you test yours?

I have a couple 6ppc barrels for bat actions lying around so i screwed on onto the action, then chambered an empty 6ppc case. the bolt wouldn't bring it back out of the chamber. Al, how much do you have to push back the shoulders on a 6br to make it shoot with the 6ppc? Please tell me more about your testing. I find this very very interesting! Thanks Lee
 
It's not so much pushing the shoulders back as chambering for a crush fit. For 30yrs people have been chambering 6BR's using SAAMI "GO" and "NO-GO" gauges like they were chambering a hunting rifle.

Then of course claiming (correctly) that they won't shoot.

And blaming the cartridge.

I have a Sharp Shooter supply built 6mmbr.It has a Brux barrel and the 112 Savage action.I shoot in modified class.My rifle is new and I have only used BIB 95 grn.with 29.7 grns.of varget.It is "short chambered" and is very,very accurate.29.7 appears to be a safe maximum in my 8 twist barrel.I am now wanting to order a 14 twist just for fun but I am retired and will have to wait.I have been using my 36 power Weaver on it but I hope to have a bigger scope by March or April.
 
Lets reverse gears here a bit, and lets talk about the 25BR. I have read a bit about this and had a couple conversations with a couple gentlemen here, and this may be something i am interested in pursuing. I get really excited about one hole accuracy, and the ppc has me really spoiled. I seem to want to base anything i build off the idea that i can achieve this kind of accuracy. Several of my close friends are into long range shooting, and i enjoy there company and want to attend some shoots with them so i need to find something that will fulfill both short range ragged hole groups and still be competitive at 400 yards. Im not real sure i can even do this but i need to try. First i though a 30x47L would shoot well at 1-200 yards and still shoot well out to 500 using randy s 130ish grain bullets, and it may be the best choice? then i thought why not a 6br with 88 grain bullets, now after i read a little on the 25br i cant help but wonder how it fits in? Plus i want to do whatever it is i do on a tooley MBR stock so i can have the flexibility to shoot some belly benchrest if the importunity arrives. There are no f-class matches in this area that i know of, but i can and have been invited to shoot along side the high power guys here at the local monthly match. That sounds like fun to me. I also have a fella building me a dedicated f-class front rest of his own design and i am really looking forward to owning it. So you can clearly see my life is a mess! LOL!! I have this one BAT MB action sitting here asking me to do something with it, i just dont know what that something is. I have the rifles i like to shoot most built just how they need to be and i don't need another anything to be honest. I like what dick said though, ( whats need have to do with it) I guess it really doesn't, but this is going to be my last build for a while and i want to make it count. So what i need is a rifle, that i can shoot groundhog matches from the bench, a rifle that will also be suitable for f-class if the opportunity arrives, and it needs to be pleasingly accurate at 100-200 yards to fulfill my internal desires. There is just something abut shooting dots at 100 and 200 yards that i cant shake!!! All logic tells me to build an 8twist 6br but I already have a 6dasher with an 8 twist sitting in a shehane st-1000 so, im not ruling that out my any means but i would like something a bit different. I shoot this dasher the least of any of my rifles, as i tend to focus on the short range games. Maybe a 10 twist 6BR? I just dont know. I still think a 30x47lapua has something to offer as well!! Thanks for letting me ramble. Its snowing and blowing here and i have a filling this is going to be one long winter. I know one thing for sure. When i retire in about 25 years i am moving to Arizona!!! I used to really like winter, but after my golden died i stopped duck hunting and i dont like winter so much anymore. Funny how things change! Lee
 
What I have always heard:

the 6 BR, when shooting short bullets is overbore. That is why folks use to shorten them up and called those by other names, Walldog comes to mind. Folks even shorten up PPC cases when they shoot short .22 bullets out of them I believe. Short and Fat is where it's at, as they say.
 
Im not so sure a 6br is an over bore cartridge, but i do think it might be better served a little shorter for 68gr bullets. I would love to pick the brain of an experienced shooter that has done this very thing. Information is very limited as no one feel or sees the need for it now that we have the ppc. I would still love to play with a shorten 6BR case and im sure i will one day soon. Lee
 
With what I have been reading about some of the later lots of the new 8208, it makes me wonder if the BR case wouldn't be a good match, for a slow twist 6mm. I think that it is really about being able to have a full case at a node. Opinions?
