When building a 6mm br should I

I am new to all of this.. I was thinking of building a 6mmbr. The question is should I have a reamer made first, that way I could take that reamer and have my dies made with it? That way I wouldnt have to make my ammo fit the chamber? Is that what most people do? Or are there other ways I could do it?

I dont think I like the idea of using bushings to size the neck. I think it would be much easer to just full length size the case and just be done with it. Am I thinking right? As I said before I am new to all of this and I am trying to rap my head around all of this.
 
DanK: My "method" is to have a reamer made to my specifications,Pacific): neck dia., chamber length, & amount of freebore. For one of my 6BRs', I wanted a no-turn neck, other 2 have .265" necks requiring outside neck turning), measured round neck dia. w/ Lapua brass is .269", so I specified a .272" no-turn neck. Chamber overall length is .010" longer than max case length. And, finally, a "dummy" round was sent to Pacific, with my bullet of choice seated to the depth I wanted. The throat was then cut so that bullet ogive touches the lands. With the arrival of the reamer & Hart barrel, all was given to my 'smith and I got what I wanted, not what someone else decided I should have. Don't know why you are against the use of a neck bushing die? With it, you control the neck dia., not the die manufacturer, who must make the die: "one-size-fits-all". The "standard" FL die will oversize, squeeze-down) the case neck, then requiring you to use the neck expander button: not good for coincintricity requirements. Also, you will be overworking your brass in the neck area, which means it will work-harden & split sooner. If interested in further discussion, feel free to e-mail me at fdshuster@hotmail.com. I don't have all the answers, but I do know a little about the 6BR, my #1 favorite cartridge.:)
 
DanK,
If you are new to this, my advice would be to find and talk to a benchrest quality gunsmith. He may have the reamer you need and set your chamber up exactly as you wish. Many benchrest smiths have finish reamers and throating reamers. The throating reamer is used to set your throat up for the type of bullets you'll be shooting.

For dies, in the 6mm BR caliber, I bought a Redding Small Base Body die. After my cases were thoroughly fireformed, I sent six or seven cases along with the die to Jim Carstensen,JLC Precision). What I received in return was a die perfectly matched to my chamber that bumps the shoulder, sizes the base, and accepts neck bushings. There are other ways to do this but this worked for me.

What are the other ways to do it? And when you say you sent in 6 or seven cases do you mean just the fire formed cases? Or cases with bullit in the case?

And if you send in the cases with the bullets seated where you want them, do you just seat the bullit where you want it and then send it in with the die without ever sizing the case. Meaning once it is fire formed you then just seat a bullit to where you want it and then send it in to have the die ajusted for it. Right?
 
You Should:

1.)Not Panic! Building a 6BR that will shoot is easy.

Lots of quality smiths will have a minimum SAMMI reamer for the bullet you want to shoot. Factory dies will work fine in such a chamber.

You sound new, what do you want to do with the rifle and how far away do you want to do it? First things first.

DanK,

I have 4 - 6BR and 2 6BRX,6BRIMP). The bushing f/L dies are the only way to go. You F/L size and neck size in one step. I use both Redding and Harrell Prec. custom F/L dies, with a wilson seater. I have tight neck and No turn necks. All new barrels with be no turn for me.

Harrell make many different size dies for a 6BR. You send him fired cases and he will fit a die to your cases. $70.00. They are as good as you can get. I just payed $200.00 for a F/L die for my 6BRX, but that was the only way to get a die for a custom round.

You should be able to find a gunsmith with the chamber you want, that is close to you. If you stay with the 6BR you want need a full custom die.

Ok, I have a better understanding now on whats going on now. fdshuster expland it to me in a way that I could understand.

Theres so much to learn.. I quess I panic a little because I was not getting it.

Does Dwight Scott still live in Michigan? He is the closest to me. Hes prolly a 2 hour drive for me if he is still around.

I was planning on making a short 18 to 20 inch barrel F-class style stock, and I wanted to use it for small game and deer. Max range for hunting around here is 400 yards, but I would also want to shoot 600 yards in informal shooting. And yes, I am brand new.. I have been shooting bows for 12 years. Now that I cant shoot bows anymore. I have to have a new hobby, so I am coming over to your side of the fence.. :D

Then after I get my feet wet a little with the 6br. I just might build me a real bench gun and start competing. Thats my plan anyways.:idea:
 
The 6 BR is real easy to load for. It isn't neccessary to get "real" involved in the process. You'll get deeper into it as you go.;)
For a chambered barrel, send a dummy round with the bullet seated where "you" want it. You can't do both long and short bullets in the same chamber and have them seated to the lands so you have to decide ahead of time what bullets you want to shoot.
Or like I did, have 2 different barrels. One set up for long bullets and one for short bullets. I like my bullets set to jam the lands and the base of the bullet at the shoulder neck junction. And both of my barrels have .272 no turn neck chambers.
I'de rather spend time shooting than turning necks. :D
Bushing dies are the way to go. I started with standard dies have added "stuff" to my collection. :rolleyes: You'll find out you can't have enough "stuff". You'll be surprised what you can do with standard dies but once you use bushing dies, you won't go back. JMHO.
 
2nd what "fdshuster" said !

I'm waiting for Hart to complete my 6mm BR project rifle.

6 to 8 weeks have turned into 10 weeks so far but Springs only

a few more months away. LOL

Regards,

Steve
 
Dan:
Your project gun sounds a tad confused. There really isn't any bench gun that's going to work for a meat maker. Not only is the stock configuration different but the bullets are too.

It sounds like a good varmint rifle may fit the bill for your first rifle. Their are others here that would know how to build those. Some of them look like they would bench well. No comp / varmint gun is going to be much of a stalking rifle though. Also, 6BR is not a very good cartridge to feed in and out of a magazine. I have a 6br repeater for Highpower shooting, but, the gun was made just for the 6br cartridge.
