Try here, this should get you started. I too have a new Dasher and have to finish neck turning my brass after COW forming in a tite neck .268 chamber.

mine will have a .264 neck. Thanks i will check it out.

The length is right around .243, and I turned down .260 and that was about perfect, it was just slightly into the neck shoulder junction (once the case was fired). So far no doughnuts. And your neck wall should be turned to .0095 and that should do put you in there nicely.

Thanks potatoe,

That's what i needed to know. Is there a way to set up the neck turner to turn .260 down on the BR neck? i Don't know never used a neck turner.

All I used was an older/junk piece of brass and slowly adjusted the cutter to stop cutting at .260 down the neck. I used a dial calipers and measured it, and its not a real science or anything obviously make sure all your cases are the same length before you start.

I was worrying myself to death trying to make sure everything was so precise and in the end I just had to kind of run with it. But I still took the precaution of only doing a few rounds at first to prep and fireform to make sure that the methods I was using would work. It will take some getting used to at first but after you get the fireforming down, its just another cartridge.
