Neck bushing issue

[Ssjimmy3]

Hi there,
I have just started using the hornady match grade bushing full length die.
I have noticed that the bushing isn't re shaping the whole neck... it leaves about 1mm away from the shoulders... what is wrong?
Thanks
James

Most bushings have an ID chamfer that prevents sizing all the way to the shoulder/neck junction. No worries unless you’re seating the bullet’s pressure ring deeper than the neck is being sized.

Nothing is wrong a bushing die generally won’t reach the shoulder.

That bit of unsized neck is by design. As RWJ mentioned, there is a chamfer or radius on the inside diameter of the bushing. This radius prevents crushing a case neck during the sizing operation. It also helps to prevent a doughnut of brass flowing into the neck/shoulder junction.

Absolutely, the die has a shelf inside for the bushing to actually lay on. The portion of the neck that occupies that particular space will not be sized by the bushing.

what is wrong?

Nothing. This is per design and desirable.
There is no 'good' in bringing donut area of brass into tension.

Regular non bushing full length dies are the same way.

Here is the inside of a Forster. I had a thread started earlier yesterday that touched on bushing dies. Looks like a fairly sharp edge on this forster full length. I can say from the naked eye..the necks are sized much straighter to the neck shoulder junction verses a bushing die.

I see what your saying, but I was just stating that the Forster fl die doesn’t go all the way down to the neck-shoulder junction either.

Are your necks turned?

Are your necks turned?

No, I am just pre-loaded really long in new Lapua 6br brass waiting on a new .272 neck build. I will find my lands when I get it and move the bullets and start a seating depth test.

Full length , turned, expander.

I have a couple Redding FL non bushing dies that size all the way down to the neck shoulder junction. Why I agree not desired its the way they only would give me .002 shoulder bump screwed down that far.

Dasher, xc ?
I think I got it from your avatar now, lol!

6.5x47

I have a 6x47 with a .272 neck and so far I have been avoiding the neck turning. Bullets don’t just fall in fired brass like some say to, but I can gently push a fired case over my loaded dummy round Bullet easily.

I have seen you post alot over the last 2 years. Don't you think no neck turned brass would have any neck tension issues? I know numerous people think, why bother. I have turned brass for oodles of factory 700s that all would shoot 1/2 moa on factory chambers. I just see neck turning as a win-win situation, regardless of your chamber size.

The new bushing neck size kit from 21st century will size all the way down to the junction. Alot of guys like to run a 1/2” end mill into their dies and get that dead space a bit shorter along with custom bushings. Neil jones makes a FL die that has the shoulder made into the bushing. Most guys also like that little unsized portion on their normal reloading (not sizing for additional neck turning) because it centers the case in the chamber as its crushed. Your bullet base shouldnt ever get there anyway. Good luck on your new BR- i know i wouldnt recommend loading brass til you get the chamber but thats just me. Sure sucks to unload em all to bump that shoulder another lick on em.

Crush in chamber, wouldn't that be like headspace a little too long causing hard bolt close? I understand the thought process of helping allign the bullet, but to me it seems no different. You are locking the case down in the chamber. I have used bushings and had good success. Custom chambers and freebores will have the bullet at minimum, into the rifling , maybe not jammed. Is there anymore need for allignment than this? Like a coax press free-floating the cartridge. Seems Free floating would exert less radial deflection and possible effects on tension during release.

I sure have nothing against neck turning and I’m sure you benefit from anything to improve uniformity in brass preparation. I do read here a lot and also see some fine folks having great success with no turn Lapua brass in chambers fitted for it.
