A 6PPC resizing die that is incrementally smaller than the chamber reamer

[ShtrRdy]

How many of you use a non-bushing full length resizing die that is incrementally smaller than the chamber reamer you use?

For short range benchrest I'm wondering if there is a benefit to resizing the entire neck such that the bullet can better align itself with the freebore and leade.

It would be nice to be able to adjust a bushing to size as much of the neck as one desires. The "pressure ring" on a bullet expands the neck as it is seated and if it goes below the sized portion, then the bullet is loose and can easily be pushed into the case.

The Short Action Custom modular sizing die uses interchangible bushings that have the shoulder and neck. This would resize the entire neck. I thought I might try one of these for my 6PPC but they won't tell me the dimensions the resizing die uses.

Aren’t they all ?

I know a Redding neck die has at least some degree of adjustment to the "depth" of the bushing. I don't know about their FL bushing die, as I don't have one.

I was told by a friend (though I haven't seen it in print) that LE Wilson directs users to machine the bottom of their neck die (arbor press type) if you want more throw to the bushing on the neck. I suppose you could also add a shim above the bushing, as there's a lot of play there.

I dont have a 6ppc.

A non bushing die, will need necks turned to fit a tight neck chamber.

I have read there are also no turn chambers .
Will depend on how your rifle is chambered.

The Redding fl sizing S die uses a bushing. The bushing can be adjusted to size a little or a lot of the neck. My 2 dies do NOT size fully to the shoulders. 243 Win & 6.5 CM

The factory 243 chamber likes about 1/2 of the neck sized. Doesnt seem to make a difference on the Creedmoor.

You need a 6ppc expert to help you. Thats not me.

Send fired cases to harrells. Get a die that is that size.
It was suggested to me to ask for a 1 step smaller than the cases called for. Because the 200 line clickers were a common problem.

Redding doesnt have enough either. Have a number of Redding dies in various forms. Wilson has even less. I dont have any Forster FL bushing dies so cant answer for those.
My neighbor has a Harrells die that not only has a bushing in the neck but also interchangeable bushing in the bottom of the die for the body/head. Not made anymore though.

Exactly what I them them, if it calls for a 2.5 give me a 3!!!

Yes...there are non-bushing fixed neck dimension dies being used. What cartridge are you working with?

On a bushing style die, you can also lower the bushing floor to size more of the neck. I have several modified that way.

Whether sizing all of the neck length helps or hurts depends on your particular combo and needs to be tested to evaluate it.

6PPC

May get more replies, if title is changed to "Need 6PPC Help."

PPC's have very little of the bullet in the neck. BT's very little, FB a bit further. I don't think I've seen any bullet go below half way down the neck. The unsized portion of the neck would then align the neck in the chamber.
Then you get into the radius mismatch at the neck shoulder junction.
My FL die sizes about 3/4 of the neck.
Is this a solution in search of a problem?

Like Dave said, the unsized portion of the neck is your friend, helping to guide the bullet straight into the rifling. As it should be! If you need to bump the shoulder get a body die, and life will be good again.

Lots of good explanation and advice. Thank You. The reason I'm asking about this is because my 6PPC reamer has a tight freebore at 0.2433. My thought being that a tighter freebore would line the bullet up to the lands. Then I got to thinking that the unsized portion of the neck could force the bullet out of alignment if it wasn't on the same centerline as the bullet.

From my limited experience it seems sizing the neck with a bushing can cause runout/misalignment. Not a lot if done right but can be up to 0.003"

Would you mind recommending a company that makes non-bushing resizing die?

I've seen for sale ads from Speedy when he's selling a chamber reamer that he has a resizing reamer for sale too. I don't know if he always does it this way?

If your throat is only .0003 larger than the bullet diameter, any neck runout will be corrected when you chamber the round.

That may be true.

 

[Ruger15151]

That may be true.

You wouldn't be able to chamber a round if it didn't.

This may be why some serious BR shooters buy a two reamer set. Rough reamer is just that. Finish reamer is a way to offer two sizes for a neck sizer...? I do with mine, and do not own any bushing dies.
