I'm gonna try to paste a few things here Mike, from when I was looking. If it doesn't work, I'll try something else but you'll get them.. Toot

Thru all my searching many moons ago Mike, I found that the most popular answer for the 22BR no-turn neck was at .254"..
Also by far most were using it for lighter bullets with a slow twist. That could be because that's the areas I mostly frequent also.
Again, mine was a .250 neck 14 twist Douglas that Fred M. chambered for me. I had no trouble touching the lands with my light bullets. I was completely new to the cartridge and turning of brass. I'm pretty sure from the replies I received that I prepped my brass backwards. Most suggested to neck down the 6BR brass to .224" in a couple of stages using bushings. One big scrunch from .243" to .224" was going to be too much.
After necking down, then turn the necks to the proper thickness. Well being new to it, and with very limited reloading tools, I attempted it. Then after necking down, I went to put the brass on my .224" turning pilot and realized that all the brass I was going to turn off the outside of my neck was now on the inside of the neck. Because I had already bought the turning pilot for .224", I was stuck..
So I started turning them in their 6mm form first because I had that correct pilot already. Then necking down with my bushing. It seems like I had settled on a .247" bushing for the .250" neck..
Forming the brass this way took a huge amount of trial and error coming up with the absolute correct thickness at the end of the process. Because the way I was doing it was actually going to create my tension with my turning.. I was using a Forster trimmer, turner tool..
After all the trial by error stuff I came up with fantastic results though. Try to follow this if I can write it down correctly..
I took my new 6BR Lapua which measured a big .013" neck thickness.,by my calipers). I took that brass, stuck it on my Forster trimmer, turning tool,Usually a 2 step process), with my turning pilot for the 6mm size. I had my turning head and my trimming head both already set up to do both trim and turn in the same process.. It seems to me that I turned them to around .011" thickness for the .250" neck. And trimmed to whatever it was. Took this brass which was now thinner material than the original, and sized it in a Redding busing die in one shot, "boom." Then loaded normally..
I want to stress that everything was done by trial, simply because this was setting my tension the way I was doing it..
Also the trim to length was trial and error. When I trimmed to .xxx" length "THEN" neck them down to .224" it would change my length.
So, it was a tremendous amount for me to comprehend as a newbie. But what I ended up with was an extremely tight fit chamber. Once this was all dialed in "perfectly",whatever my actual numbers were). I could go through all that prep work, load, and shoot. Come back to my reloading press and "skip" the sizing die completely, and just prime, charge, and seat. Go shoot and do it again.
What was happening was my loaded round was at the very most snug size to allow the bullet to release and fire, the brass would expand and contract during that process and have the perfect amount of tension for next time. It may have even been technically unsafe, but I never had a problem with it.
The brass after I fire all my other guns is like this.. I can eject them from the action, and take a bullet and I'm able to slide it back in because the brass has expanded to the neck, and bounced back, still having enough room for the bullet to slide thru. I liked using very light tension. This gun would give me back a piece of brass that was ready to seat another bullet and still give me close to .001 tension. Maybe a hair less, I didn't use much tension..
I don't know if it was dangerous or not, but it sure was "COOL"!!!
I don't think you can avoid using either bushing dies,my recommendation), or going with a total custom set.
Well, you said you wanted something to read on the subject. As usual I probably got WAY carried away. But it brought back memories, and I got excited...
