Is there anyone out there that will neck turn 6 BR brass to your specifications? Someone told me that you can have this done.

Thanks. Anyone else? I like choices.
Brass prep is/can be a tedious task. But.. a neck turning service? I'm missing something here. After fire form the previously turned necks usually require a second prep. Do you then send the brass back to the neck turner for anneal, trim and turn? Is there an extra charge for dough nut removal? This all seems too gun/chamber specific to be done correctly without actually having the specific gun in hand. The
next question that comes to mind is; how much neck release/tension, .002",.001",.004"? After the dough nut is removed by reaming, how much over cut should be specified and will the "service" single point taper the shoulder junction inside to avoid further development of the dough nut squeeze? I'm clearly over complicating this process. Must be a Dasher thing.

The guys that do it charge too much in my opinion. Or more than I am willing to spend.,$1.00 a piece, with me supplying the brass) So I set up and did it myself. I was making a big deal of it. To me its pretty easy. jaws

Yes, you are over complicating this whole thing. Several sources do have neck turning services and have plenty of work doing it. Its too time consuming for some to do I guess. If you know the neck diameter of the rifle, then turning necks to the right thickness is a simple matter of basic math. A neck turned properly the first time won't develop a donut for a LONG time, if ever in the life of the case.

Take a new 6br case expand it with a K&M expandiron then don't neck turn it just run in the dough nut cutter. See the shiny ring down by the shoulder. Think your neck tension might be inconsistent?

I'm not saying that all the brass has one, however I've tried it on about three different batches at random with the same results. The Dashers don't usually dough nut,so far only a few)I've never seen it on the bullet jammed fire forms but have noticed it on the expanded shoulder forming technique. I picked up on it while neck turning some thicker than usual necks on standard 6BR Lapua brass. I have a couple different 6 BRs and I was getting pressure signs with "safe" loads concurrently in two different guns with unfired un-turned brass. I'm going to cerrosafe all my chambers to determine the actual chamber dimensions. I also noticed that the dough nut seems to be harder and stronger than the neck as you can feel it "hit" the ring if you are careful when seating with a lubed Berger VLD right at the beginning of the boat tail transition. It's like a little bump. This happens even after I ream it with the remover. The best and worst,as in hoaky) way I've found to eliminate it totally is with an old jack knife that has been sharpened too many times and the blade is pointed. I over-cut it and then when I turn it I over-cut with the turner.

Al,
You are correct as I never get to the shoulder junction with the 6 Dasher that I bought from James Phillips. With 105 Bergers just touching the lands which I believe was chambered by Mike Bryant,however,I just measured another Dasher which was barreled by a local on a Remington and just touching the lands has .699 of an inch less free-bore. This gun shoots good but requires an entirely different seating depth which with 105s or 107s puts the bullet's boat tail transition on the shoulder junction.
