Inside the neck donuts

[243winxb]

Ream first, then outside neck turn to the finished neck wall thickness.
This should make the wall thickness uniform.

I used the LE Wilson inside neck reamer until I watched this video. His recommendation around the 3:30 mark is to use a bushing die; works like a charm for me.

I remove mine with a forster neck reamer

Ditto,
Forster internal reamer
------------------------------
Take measurements
You usually want to internal neck ream AFTER it has been shot and the neck expanded
If you ream the inside before hand, it may not squeeze down enough to hold a bullet
------------------------------
Or use an expander mandrel
------------------------------
Ebay also has Chucking reamers you may be able to find your exact OD reamer needed within 0.0001"

I check mine with a gauge pin that barely goes into the fired neck. If the pin stops on a donut, it gets reamed

Would anybody have a picture of the donut ring inside the case. I do not believe I have ever seen one before. Thanks

One thing I'd like to ask,
If the bullet does not get seated down that far
What does it matter if theres a donut?
------------------------------------------------------
I ignore it if my bullet base doesnt come near the neck/shoulder junction

The O.P.'s situation is that to fit in the magazine, the base of the bullet ends up below the donut.

Use a bushing die and only size about 75% of the neck. The donut will be below and bigger than the sized neck id.

Not a picture, but all I can find. R-clicked from somewhere on the internet.

I didn't even know such a thing existed.

As long as the bullet base is above the donut many say it doesn't hurt anything.

HENCE "Why" I LIKE, the Longer Necked Cartridge, designs,.. Like, the 6 XC !
And the 6.5 Creed's "Neck" length,. Ain't Bad, either, using, Boat tails and COAL's in excess of,.. 2.835"
Doughnuts have NEVER been, an "Issue" for, Me with, either Cartridge..

Run a mandrel in the necks, push the donuts to the outside, then turn the necks.

Exactly!
