6BRX Dies -- Source, Full-length Sizing?
- Thread starter Forum Boss
- Start date
Hello Fellow Shooters,
I have had some calls and e-mails on sizing dies for my 6mmBRX and have a very simple soloution for you.
I personally have not had any base expansion problems with the 6mmBRX as I only shoot @ 3033fps. and have NO pressure signs at all. But--when load searching I have indeed wandered into the upper reaches of max and above? and while doing so have swelled a few cases myself.,3200fps+ is there--but NOT SAFELY!!) Anyway, I have a very easy fix for those of you that feel the need for speed.
Purchase a body die from Redding,$20-$25) and take it to your favorite machine shop. Have your smith ream out the top 2/3rds of the die to a 1/2" inside dia. Leave the bottom 1/3 alone and you will have a full lenght,read: base die) die to suit your needs. You can even cut off a bit of lenght from the bottom of the die if you need more base compression for those of you that find you have a tight chamber. This is a piece of cake to make and works perfectly! Remember--you will not need to use this die EVERY time you shoot, only when you feel the tight bolt.
I have used this method for years now and figured out how to do it when I made the 6.5mm.SUPER. You will find no problems with this easy fix.
Good shooting!

I too have made a base die using the method Bob Crone describes. It works fine. However, it means you end up using a 3 die series to size cases. Those shooting this cartridge in High Power will find the 3 die process tedious. I have a full length die coming from Hornady. My experience with a Barnard action with a snug chamber is that the base will need to be sized. A two lug action may not need it if running velocities very near to 3000fps. It is a superb cartridge Bob. Thanks for your work.

Scott,
Thanx for your input. Would you please e-mail me when you have tried the Hornady die with your impression of it's performance?
I do not need it myself but there is a growing market for an in-expensive die as such.
BTW--At the 2005 F-Class Nationals held in Oak Ridge Tenn. a new world record for f-class was set with a 6mm.BRX.,150 with an X-Count of 27 or 28. @ 1,000yds.) I don't have the shooter's name in front of me at this time---kinda wish it was my bride tho as this is her round of choice. She did break the range record at Butner NC. in 2002 on her second F-Class match ever.
She shot a 200-15X @ 1,000yds. All while fire-forming brass with the 6mm.BRX.
Needless to say--I mind my P's and Q,s around the house so that I don't get her mad at me. She shoots too good.
Good Shooting,
Bob

Hi Bob,
I will let you know as soon as I recieve the die. Along with the growing market for the dies, there is a wish among many of us for brass that has a little longer neck. The BRX cartridge is the perfect choice for X-course. It has supernatural accuracy, long barrel life and superb long range ballistics.I am currently putting together a tube gun for X-course in the BRX.
I shot a 199-12X at 600yds in Coalinga 2 wks ago with my BRX prone gun with irons.
If you would contact me by email at vld223@yahoo.com, I would like to discuss with you some ideas about bullets.

Hi all i was deciding what to chamber my last rifle for and the two choices wer 6mm Dasher or 6mm BRX i went with the 6mm Dasher as bushing dies are available from Redding as semi custom they keep them in stock i cant see the point of using a neck die then a body die and then another modified body die if the shoulder and base dimentions are the same then the angle on the side of the case must be different if it is tsreached 100 thou. Even though this might be nit picking i would rather a body die or a Type s full length die as i am usnig.
If Redding made a BRX die and not a Dasher die i would have chambered my rifle for it as i believe they are just as accurate as each other. JMHO

Bob, I wish it had been 27 or 28, and it could have been, but I wasn't paying attention to point of impact gradually dropping and my 24th shot just leaked out the bottom, leaving me with 23 x's for the record.
I get a little pressure,very slight primer flash) with 107 SMK's at 3025, but shoulder bumping every time,with Redding body die raised in press) after 4th-5th reload takes care of potential sticking. After 20 reloads, am seeing about .0005" swell at base of web.

Sounds good. What was purchase price? And how much for shipping?
What was turn-around time for you?
Was there a print number other folks can reference for future use or will Hornady only work off fired cases.
Did you have the neck diam. set to size your neck or will you do that with bushings?
The die was $75 I think. The turn around time was about a month. They have a copy of my reamer print. They also used my fired cases. The Gentleman's name is Lonnie Hummel. The die sizes the brass .001" at the base, .0015" at the shoulder and bumps the shoulder .002". I now have a one die process that is perhaps as close to perfect as avaiable.

Scott,
Does the die itself bring in the neck or do you do that with bushings?
I agree that the one-die solution is elegant and effective. $75 sounds like a steal if it proves to work well.

So about how much neck tension is the die giving? With the Redding FL 6BR die I had reamed,to reduce the amount of neck reduction), the neck, when it comes out of the die, is about .0017 less than the diam. of a loaded round.
