6brx vs 6dasher?

[deadlyswift]

I have about 3 weeks left on my wait for my two barrels. I'm still undecided on witch way I want to go. I need to make a decision so I can get reamer spec's together and call PT&G. IMO the 6brx and Dasher are pretty much equal as far as performance down range. Where my delimma comes in is what are the pros and cons of fire forming, reloading, and reamer spec's?

First thing I think of with the 6brx is the shorter neck. I wondering If this will cut back on thorat life? I do want to try and start out with the bullet touching the lands, and the bearing surface apporxmeantly .050 above the shoulder/neck junction. Would throat life be longer with the dasher since there is more neck to seat the bullet further into? I'm just one of those shooters that likes the shortest thorat that I can get with the bullet just above the shoulder/neck junction. With the 6brx having a shorter neck, am I right to think that I would run out of neck quicker in the 6brx than the dasher?

Second thing I am considering is dies. I already have 6br dies so that saves money as to not having to buy custom dies for the dasher. However is that savings worth it if I have to give up on throat life?

I'm looking for opinion's on case performance and throat life more than the performance down range. I just seem to think the two are equal as to down range performence, but trying to decide witch would suit my needs best as far as fire forming, reloading and throat life? Please fill me in on the pros, and cons as far as loading, and throat life?
Thanks
Mark

Mark,

I have shot a 6BRX for 6 years, If you run out of neck on a 6BRX, your barrel will be got anyway. Don't pay the money for custom dies for the Dasher, go with your current dies. But, the two are so close, just flip a coin.

I have Dashers and BRX`s and BR`s, but between the BRX and Dasher, I feel in my heart the BRX is a more better round. I just came back from my first ever trip to Piedmont, NC and saw some of the finest shooting I have ever witnessed. The guy shooting heavy gun shot a BRX smithed by the very talented Mike Davis. He agged a 1.7xx". There was more there to see and bear witness to this, in my humble opinion. I own 2 BRX`s one by Davis, and can say without reserve that these barrels I either got very lucky twice in a row with 2 different manufacturers, Brux, and Krieger, or the chambering makes the difference. I came away with so much evidence, I called Dave Kiff today and ordered myself a BRX no turn reamer. I already have 2 of them with a .269" neck. I chose a 1.570" chamber length, and a .170" freebore because I too like the bearing surface out of the neck shoulder area. With Berger 105 VLD`s so out of tune, I wanted something set up for Berger 108`s and Sierra 107`s,and a possible 108 BIB in the mix. Good luck with your decision. Tim

The custom dies that I use for my dasher are an off the shelf redding s FL die and a forster micrometer seater die. The set runs about $150 from sinclair. That is not real expensive in my book. I haven't shot a brx yet but I couldn't do without my dasher

I'm just a rookie at this and have a standard 6BR. I presume you have seen the interview with Dave Kiff at this link:

He obviously is a fan of the Dasher. My thoughts are that there is more flexibility in having a longer neck. You can have an effective short neck by just sizing a portion of the long neck. This also can avoid interference with a potential donut if you seat deeper. It also allows the initial throat to be a little shorter, allowing more burnout allowance.

deadlyswift,
I have never owned a Dasher but I shoot a BRX for varmints and I absolutely love it. Great velocity and accuracy with 75 grain V-Max bullets over Varget powder. It really is a simple proposition. Since you have the 6BR dies, I would lean towards the BRX but you can get in the Dasher game by selling your BR dies and putting that money towards Dasher tools. Either way, you won't regret your choice. Just my opinion.
Don't forget that you will need to size the base of the BRX case with a 243,30-06, etc. die to avoid the "click" at the top of your bolt lift. This is caused by raising your BR dies approximately .10". Good luck on your new project.

I don't think you should base what chambering you go with on what dies you have on hand. Go with what you feel is going to suit you best and fill your needs. It would really suck to go with something based on having dies for it, only to look back and say "If I had only spent the extra bit of money on the dies I would have what I really want."

After buying the barrel, reamer, brass, and paying to have the barrel chambered and threaded, dies really are not that much more of an investment.

Sinclair sells Dasher dies, so you don't really need custom.

Maybe I just think and read too much! Kinda like Mark Schronce said flip a coin. I guess it really comes down to my concern of Throat life. I say throat life and not barrel life simply because the throat is the life of the barrel. So how many rounds are you guy's getting out of your 6brx, and how many rounds are you dasher guy's getting out of your dasher? Is there any clear proof that the longer neck in the dasher is helping out with erosion? Again I'm really not worried about down range performance Both are really equal in that aspect. I'm not too worried about having to spend 150 or 200 more bills for a set of dies, but If I will get the good out of my barrel with the short neck of the brx $200 can be spent on bullets, primers, powder etc instead. It's not as much as spending money as spending money the most effiecent way, and giving ME (note me is in caps) more range time! ;D
Thanks
Mark

I've shoot the 6 brx for the nmc at butner and long range for quite a few years now and it is a great shooter, i had the 6br dies along with the .308 base die so it is a no brainer, vs the dasher for me when i decided to shoot a 6mm that was better than the 6br vs a .223 or a .30 cal. the 6brx is good for 3000 rds of barrel life for me and that is it, replace it and move on. davek.

My thoughts are that the longer neck will do nothing to prevent throat erosion. What it will do if you chamber the throat short, is let you initially seat the bullet further back in the neck, and then move it out as the throat burns out. So the net result is longer life in rounds fired, but does not prevent actual erosion. As far as throat (barrel) life, I believe it comes down to how much powder do you burn. The cartridge that takes more powder will likely burn faster. Still a long throat will help you minimize the effect.

 

[Kenny474]

I tend to disagree about throat life of the Dasher. I feel the longer neck and improved shoulder angle will extend the life of the throat by at least a decent amount. The steeper shoulder will keep some of the gases inside the case from the increased turbulence, and the longer neck is going to be shielding part of what will be throat in the BRX. It just seems to make sense to me. Maybe I'm wrong.

I'm on my 4th BRX barrel now. They'll go 3000 rds. without a set back. And approx. 3500 rds with a barrel setback. All 4 barrels have shot .4in for 10 shots at 100 yds. I'll be surprised if the Dasher will give you significantly more barrel life.

kenny,
I am going through the same brain trama as mark 6brx or dasher? are you saying your thoughts are on the dasher over the 6brx and why? give me your thoughts on + and - of each cartridge if you would Kenny. Thanks
Wayne.

 

[spclark]

If you have barrels nitrided they'll probably last twice as long too. Pretty inexpensive way to increase barrel life no matter what chamber choice you make!

 

[bozo699]

spclark,
I don't know much about nitride? what does it do for you? who can do it for you? and what does it typically cost? are there any - side effects? Thanks.
Wayne.

I did a search on here and read all the posted info, then I called the Indiana plant and talked to the head guy. The Indiana plant is the one that will do the process because that plant's capable of the exact temperature for the process which if I remember is 980 degrees. This process will give you extended barrel life, so far at the plant reports are at 10,000 rounds of accurate barrel life. This could be a .308 but they normaly go about 5000. 1 barrel is $100.00, if you send more out the cost is reduced. 3 of us are sending 6 out and the plant told me that it will be 40-50 $ a piece. Almost everything about the treatment is positive, they also clean easier. The S.S. changes color to a black. Back to the OP, those are two tuff calibers to choose from. I have often wondered myself, that is why I've been keeping up on this thread.

Donald,
Thanks for your resurch, I plan on possibly trying this on a new build to see if it does work,if it does the $100 would be cheap.

For real?
It would be great!

I have been shooting a BRX for a couple of years now and i'm very happy with it my heavy gun shoots very well in the BRX. I am fixing to try a Dasher myself just to see how it stacks up I know alot of the 1000yd guys are shooting a dasher and having good luck with it.

good luck with your new project
