6talldog

[Bret]

I currently shoot a 6MMBR with very good results. I have heard about a wildcat version of this cartridge called a 6talldog. That is said to be the best wildcat version of the BR,,capable of PPC accuracy, or close) I am an avid reader of this website and have never read of this cartridge. Can anyone give me any information and/or specs of this chambering? I shoot 200yrd. benchrest in the winter months with a local group with some pretty crazy wind conditions and temp. changes here in SE Ohio. I am very satisfied with my Bob Green 'smithed BR,it is alot more capable than its driver and I sure will have him build my next toy.I guess that I am just looking for a few less thousants on the target without the PPC chambering. Call me hard headed but I've seen the BR's shoot with or close to the PPC,and beat it) in our group, and all of them were 'smithed by the recomended gunsmiths on the 6BR site. Thank you for any help with this question, Bret

A Talldog is a 6 BR short chamber. I beleive .075 short or so. The Walldog is .115 short. Br shooters beleive that the 6 BR has to much poswder capacity and reduce it by shortening the case.

There are several versions of a short 6BR, the Tall Dog being just one. They were all developed in the last Century when shooters were still trying to find a combination that would equal or beat the 6 PPC. None of them did. For the longer distances,400 yards plus) the standard BR or one of the full-length wildcats are sufficiently accurate so the need for a short 6BR is non existant. Unless you're an avid wildcatter and just like to play with that sorta thing.

The Waldog is a short PPC, not a short BR. 22 caliber. There are several versions of it also.

Guys thanks for your reply about the 6talldog! After reading that I wonder if the 30BR would be a better choice, taking into consideration of the wind factor and temperature changes on our range, because it is not a flat range like most. 15 to 30 MPH gusts are common every week and I would like to find a cartridge that would buck the wind a bit better at 200yrds. Yes we do use Sinclair wind flags, to the best of our knowledge. As I said before, my 6mmBR shoots fantastic but I would like to add another toy to the safe for 200 yard shooting that would help me play the wind and beat the boys! I have another friend that shoots a 6BR and he is talking about trying a 30BR and I certainly cant let him get one up on me! I have read the Info page on this site and it seems to be a very interesting chambering,granted,we are group shooting and not score shooting but accuracy of this cartridge is certainly talked up. I am including a picture of my BR and a target from last year. The center to center measurements are L-R .363,.208,.241,.345,.235. The rifle is a Ruger M77 MK2, 6BR Broughton Barrel 263 Neck, T36 Scope,'Smithed by Bob Green.

Bret, I shoot a 6BR -.100 in BR competition and It shoots right alongside all the 6PPCs and holds its own very well. It shoots much better than its shooter.

I like this chambering because it uses the .308 boltface and Lapua brass for it was cheaper by about $5-$10 a box...not sure what the new prices will be, but we'll see. The case forming is more labor intensive, but when you're finished with all the prep, the fireforming step doesn't change the dimention of the case as radically as fireforming the 220 Russian to PPC.

With all this being said, you might want to look at what my friend Jackie Schmidt is doing with the 6BR project to shoot heavier bullets in his rail gun. This got my attention, because I am thinking about a full length 6BR barrel for one of my rifles in a faster twist like a 1-10 to shoot heavier bullets here where I live in Texas where the wind blows all the time on match day. I really interested in what Jackie finds when he finally tests the BIB 95 grain bullets.

I got excited about a project like this when I read an old article in the Wildcat Cartridge Book that described a chambering like this for primarily 200 yd BR competition in windy conditions.. It shot very well at 100 yds too. They used a .308 parent case, before the 6BR came on the market. Their results were outstanding to say the least. The article states that a case the capacity of the 6BR with heavier bullets up to 90 grains will have the wind cheating properties of a full .308 shooting 168 grain bullets. They tested this with a 1-12 twist barrel. With the heavier bullets, like the BIB 95s the twist needs to be 1-10. Jackies test uses a 1-8 barrel.

This might be just what you're looking for, I knbow it is for me.

Thanks Bill for your input on this subject,I received an e-mail from my gunsmith with the same deminsions for the case, his talldog answer) but haven't had the time to talk about it any further, do you know were I can find any more info on this case? You mentioned the case forming to be very involved,what steps do you take? I would be willing to do the work for more accuracy.Also,where can I find the article or info on Jackie Schmidt's work with this case? Thank you for the info,Bret

Bret, I said that case forming was more "Labor intensive" not necessarily more involved. The only extra 2 steps are pushing the shoulder back the desired amount,do this in a shortened 6BR full length non bushing die) and trimming off the excess .100 inch...that's the part I hate, trashes my fingers and wrists for about 2 days and I use a power trimmer.

Only those of us who shoot them have much info on the short 6BR, but I will say this, it's a natural chambering for a switch barrel rifle that's also gonna be a 30 BR One kind of brass to buy, one kind of powder to buy,Benchmark)...Shelley proved that one for us, and my short 6BR loves benchmark. We've gone as far as dedicated -.100 6BR reamers ground to Lapua brass specs for our rifles instead of short chambering a regular 6BR.

Bret, The Main board on the forum here is where to find Jackies test info and findings. He's also written some things on the Benchrest Board, but mostly it's here.

Great stuff.

We are trying to hit the highlights. But keep in mind that Jackie has a big folder of data, and so far I've been making do with phone calls and a fax or two.

When the entire project is complete it will be the subject of 2 or 3 extensive articles. Don't expect a lot of pretty pictures though--Jackie's too busy loading and shooting. But we are learning a lot of useful stuff.

I won't say Jackie has rendered the 6BR improved obsolete, but if he's getting 3000 fps with a standard case, it really opens up a bunch of new possibilities. I know at least 6 people who have started testing RL15 based on Jackie's findings, and a couple guys now have the courage to experiment with shorter barrels, since the velocity gain of 29" or 30" over a 27-28" is less than many folks predicted.
