6 Dasher hydroforming and neck turning

[Ajwilly96]

I will soon have a tight neck 6 dasher barrel, and I was wondering what the preferred method is.

Do you generally turn the necks as 6BR cases then run them through the Hydroformer, or hydroform first then neck turn as a Dasher?

Personally I would turn them first, so part of the 6BR neck becomes part of the 6Dasher shoulder. Eliminating having to turn to the shoulder, if turned as a formed 6Dasher. Hopefully this makes sense.

Back in the days when I did fireform from 6BR to 6 Dasher (I don't any more), I would neck turn twice, once up front to get the brass uniformed as 6BR, then another touch up after that first fire-cycle.

These days I just run Alpha 6 Dasher brass and I don't bother turning at all. I should note that I am not a benchrest competitor, I shoot sling so anything below 0.4 for 22 shots makes me happy.

Hydro-forming dies does a better job if necks are not turned prior to hydro-forming. I will not hydro-form any brass if the necks have been turned. I would have hydraulic fluid sprayed all over my shop if I did.

I thought I was doing something wrong. I always hydroform first and then turn necks. Works out just fine.

Peterson Dasher brass works pretty good too.

Good to know, thank you for sharing your knowledge sir!

I always turn the Br brass to the desired thickness.250” from the case mouth. After trimming of course. Using water, hit the punch 3 times with a medium ball ping hammer. Set the die in the press so your brass is .003 longer than your max headspace. Bump shoulders back in your sizing die and you are good to go.

Just get Alpha OCD 6 Dasher brass. No need to get 6BR brass and hydro/fire form it with Alpha 6 Dasher brass around.
