Does anyone other then redding make a 6BR body die. I have a redding body die and it does not size the case enough to chamber in any of my three factory 6Br rifles or in my custom. yes I tried a different shell holder, same problem.

I guess i shouldn't say wont fit, i can get it to chamber but its really really hard to close the bolt. If i run the case through the die three times its not as hard but still tight to close the bolt.

If i use the RCBS full length die then they chamber after. but i want to body size and neck size seperatly
 
Forster makes a "Bushing Bump Neck Sizer" die in 6BR... without the neck bushing installed it's just a body/bump die... add the bushing and it bumps and neck sizes all in one go.
 
I have a Redding body die I use for my 6br and have had no problem getting it to bump the shoulder back, It does what it's supposed to do.

That said, you should try a different shell holder as the one you have may be a little out of spec, failing that have a few thou taken off the bottom of the body die.

Like mentioned above, I have tried two different shellholders, same problem.

I'm thinking it will be about impossible to take any off the bottom with out taking way to much, and pretty hard to keep it true.
 
Shorten the body die. The die only sizes the shoulder area and shouldn't touch the base anyways. Even if there is a gap between the die and shellholder, doesn't matter.

If the problem is a fat base, then check the action for proper lockup and use a small base die.

if you find the RCBS sizes the way you want, just open up the neck portion of the die and turn it into a body die.

I think what you are saying is that even if I did shorten the die to much I could just leave some space between the die and shellholder when sizing? I guess that's true, or I could buy the redding shellholder set that comes in different lengthes. Know anyone who can trim this for me?
 
your going to need a small base die regardless of neck sizing or full length sizing. The base of the case it to large for the chamber, your shoulder is likely in the right spot but you need a bulge buster sizing die so to speak. the redding body die will fix your cases

UMMMMM I am using a redding small base body die? and it is not the base it is the shoulder that is not being bumped back far enough. You must not have read the beginning of this thread or something?

You can cut the die in 1/2 and it will not change the end result. With custom chambers, I run into this from time to time as die makers can run to max possible length when they make the die. max dim die vs min dim chamber, you have the problem you face.

I just lob off the bottom a bunch - doesn't matter what - then turn the die in very small increments until I size exactly what I want. As long as the die is above the shellholder, you know you can always bump further.

I do not use these specialty shellholders. I never saw the point.

The fear of machining the bottom of the die is likely because you don't understand the case will self align in the die. Just wobble the case in the shellholder to understand, the shellholder is NOT what indexes the case in the die. It is simply the "finger nails" that grabs the rim so you can pull the case out of the die.

sorry.........I have the opposite issue. Shoulder can be pushed back far enough but the base of the case is to bulged for the chamber. You might want to play with a jiffy marker on your brass to see if you have the same issue..........the redding dies are over the spec of my chamber.

If I take a fired case that fits easily into my chamber and shoulder bump neck size the brass I can close the bolt with no drag, if I full length size a case I have to force the bolt to close. I suspect you maybe having the same issue but blaming your shoulder location.......

Okay, I hear what you saying. I guess i just always figured that the die can always wobble in the threads in the press a little. The shell holder can move in the ram a little. I kinda liked having the shell holder and die come into firm contact thinking that they would maybe line up true with each other keeping everything nice and straight.

I never really though about how much the brass can move in the shell holder anyways. It does move around a lot.

And the brass would already by sized funny most of the way if you where waiting until the last little but for the shellholder and die to come into contact to keep things true.

only nice thing about having them come into contact is that sits easier to keep everything sized the same every time.

but if its not sizing enough its no good anyways. and every chamber is different also why not size exactly rite for the chamber.
 
Took die to machine shop, they are removing 0.004' that should be enough, if not i can always take more later. Just didn't want to trim off to much and lose the nice radiused part at the start of the die on the inside
 
Took 0.004" off the die but it didn't help any. Going to take another 40thou off the die. In worried that if I have to get the brass that far in the die to move the shoulder enough that I'm sizing the body down way further then it needs to go?
