I'm starting with new Lapua 6BR cases and Redding Competition dies. I notice even the FL sizing die with bushing doesn't resize the entire neck to the shoulder. The Body die only sizes the shoulder and body. I'm left with a small section of neck just in front of the shoulder that is greater in diameter than the bulk of the neck. If I were to turn case necks, that part of the neck would not be uniform with the rest. Not saying I need to turn necks at all because my chamber has a .254 neck but this is driving me crazy. Do I need to buy a Forster FL sizing die in order to resize the entire neck? I notice Redding and RCBS only offer bushing dies in that caliber. Also - that un-sized portion of the neck causes the case head to protrude too far out of the base of a Wilson head-space gauge. Any thoughts?
First time reloading for the 22BR - FL sizing?
- Thread starter barrowsr
- Start date
That small unsized section will not hurt anything and may help with case alignment in the chamber. A full length die will size all the neck if needed for turning. Carry on.

When necking down a case with a bushing, you will run into this (problem) as others have mentioned
it won't affect much. Also when necking down a case, the necks are usually thicker than normal.
Once I fire form the cases, I'll figure out what I need and order a custom honed FL sizer
from Forster. Always error on the small side. You can always use a mandrel to open up
or use to push out the neck, you can't if you make it too big. Then it defeats the purpose
and might as well get the bump bushing neck sizer.
The FL sizer will do all in one step. Set shoulder back, size neck and case.

Its fine. No worries
Easy enough to do yourself with a minimum of equipment.

You need to get the virgin Lapua 6BR necks under .254 (the chamber neck diameter) all the way to the neck/shoulder junction for the initial firing.
After the initial firing, you can have a portion of the lower neck unsized as it's now a bit under chamber neck diameter...due the the spring back of the brass (in theory).I don't like this for a number of reasons, but that's for another time.
I've done a good many 22BR's and use a Redding #91316 22BR standard, full length, non-bushing die to size to size the cases initially. It will size the necks all the way to the neck/shoulder junction.
Good shootin'.

-AlI always wondered why bushing dies do not size the neck above the shoulder neck junction.
Then it dawned on me, why size the donut and make the neck ID smaller.
Below the red arrow points to the area of the neck not sized on the Redding bushing die. Notice how far above the neck shoulder junction the bushing is and how much is not sized.
Bottom line, if you need to turn the necks get a standard non-bushing full length die. And use the WFT that trims the case off its shoulder, that way your cutter always stops at the same point at the neck shoulder junction.

You like to post that picture of the defective bushing die. I have never in all my days used a die that was that far off. I guess if i ever do run across one ill fix it.

All my bushing dies are set up to size the entire length of the neck. On the Redding and Harrel's, the floor where the bushing sits has been lowered and a spacer made to fit above the bushing. On others, Redding Body Dies have been converted to accept a bushing and a decapping stem. Both ways work well.

I've done the same. Use carbide tooling. That part of the die seemed especially hard.
I recieved a custom honed .223 die a mounth ago and as of this mourning they are still listed on the forster web site
some info here. http://forum.accurateshooter.com/th...ass-from-6br-neck-area.3947544/#post-37175856
I found that sizing down the 6BR brass made it too thick (?) + inside reamed the necks with a Wilson neck reamer. perfect .0015-.002" bullet/case tension afterward - for me, anyway.

Must be a lot of defective bushing dies floating around, the website below shows the same thing.
Case Sizing 1: Sizing Die Selection
http://www.mssblog.com/2016/02/02/case-sizing-1-sizing-die-selection/
"Neck-bushing-style dies (in conjunction with full-length sizing die body) seem like a really good idea, and they can be — but they are another step in controlling case dimensions that most of us don’t want to take or need to take. My biggest issue with bushing dies is that they don’t size the full length of the case neck, and that can create problems. The arrow points to the small area of the case neck that is sized."

Just for clarification on the 22BR, are those that aren't turning necks having issues with the bushing dies? I turn my necks on the 22BR before the neck down operation and have modified my die as Al noted. I haven't run in to any problems with donuts or concentricity.
