6mmBR dies?

When seating bullets for a 6mmBR is a competition seating die needed? I have been looking at dies and so far think I am about getting a Redding Type S FL die with a few different bushings but am lost as to what seater to get.
 
Do you have a special chamber in your rifle requiring you to turn case necks and use a bushing die?

Why are you getting a bushing FL die. It would make more sense to get a bushing neck sizer, and an inexpensive body die (IF you really feel the need to FL size once in a while).

I shoot a 6mmBR with a 0.262" neck, and I use the bushing neck die and it is more than enough - you will not need to full length size the case every time you load it.

As to bushings, they are expensive - try to find what you need before you throw money at Redding

Do you have a "tight neck", a "no turn neck", or a plain ol' sloppy neck??

The loaded neck of a no turn cartridge should be ~0.271" to 0.0272".

The chamber neck should be 0.003" to 0.004" larger then that - so look for a 0.275" to 0.276", and it should be marked on the side of the barrel.

The die set you might consider is:

1 - Redding Bushing "S" neck size die.

2 - Redding TiN bushing - 0.270

3 - Redding body die.

4 - Forster Ultra seater die.

Those should get you started with good stuff that is match capable.

One last thing. I asked this question on a different forum and they said go with the FL bushing die. That is why I asked. I want to buy the right dies the first time. I am trying to learn as much as I can about all options.

That depends on the brass you are using. I would suggest deciding on the brass you are going to use and then research the loaded round diameter. At that point you can decide what bullet you would like to shoot, because they will determine the free bore and neck diameter of the reamer.

Are you planning on shooting competition?

What is your plan for a chamber. Does someone have a reamer or are you going to have to get one?

The blue box is running .268-.269 loaded round with unturned necks. One of the most popular reamers for no-turn blue box is a .272.

The Berger Hybrid is doing very well and I would recommend it. IIRC my reamer is .100 freebore. Could be .104, I will check when I get home. It puts the 105 Hybrid just above the shoulder/neck juncture so no concerns with donuts. Varget and 450s is doing very well.

My opinion, I don't think a "non-competition" seater will hold you back as long as the quality is there. There are many other aspects that will affect accuracy more than the seater used, unless you end up with a real turd. However, if there is the chance that this project might lead to comp at some time in the future than spend the money once and go for the comp seater.

I will get back to you on the sizing dies. Gotta go.

Most benchrest guys are bumping shoulders every time they reload. If you are going to have a custom chamber and your goal is to get the most accuracy from your rig, you should probably think along those lines. Their goal (the BR guys) in case prep is to produce a very consistent case with very consistent neck tension. Neck sizing (alone) for the most part is not in favor.

I will tell you what I am doing and you can go from there. I am using a Harrels die to bump the shoulders and size the neck. Harrels dies use common bushings to control neck tension. I am presently using a bushing .002 less than my loaded round diameter. The reason I am using the Harrels is because it is a custom die that doesn’t over size the base. Most SAMMI dies are going to size the base more than I want, and the expensive Lapua brass is going to last longer without that. Also, the case is going to fit my chamber better than a case sized in a SAMMI die. The Harrels die is a real deal as far as I am concerned. I sent in three cases that were shot several times in my chamber and only neck sized. For $75 Harrels sends you back a custom die.

If Lee would get off their butt I would order a 6BR collet die. The last I knew they weren’t making any custom dies. Eventually I would like to use the Lee collet die to size the neck and the Harrels without the bushings to bump the shoulder.

The reamer I have is .2704 neck, 104 freebore by the way.

Whether to use a neck or FL die depends on what your goal is.

"Point Blank" benchrest shooters (100 and 200 yard) use FL dies, NOT because they are more accurate, but because they must have easy, smooth chambering during a match - they shoot their groups very quickly when the wind drops and they cannot have the rifle move off of it's aim in the sand bags because the case was tight and closing the bolt moved the rifle.

600 and 1,000 yard benchrest and match shooters use neck sizing dies because they are more accurate - it is not my opinion... it is what it is.

At $1.00 a case, you want the brass to last.. neck sizing will assure you the best of everything.

If you get advice to use FL dies, pass on it, it is from someone that reads about benchrest, but doesn't actually shoot it.

Again, thanks for all the info. My goal is to get the rifle shooting and then be able to load up 20-40 rounds and hit the range. While at the range, I want to shoot from 100-500 yards at different targets. I enjoy shooting and reloading. I want an accurate round that will not eat up a lot of powder, is accurate, and will not pound me as I shoot it that is why I picked the 6mmBR.
