Why does no one make good 6mm dasher brass?

[horsemen61]

Walkalong I throw this one toward you mainly because your buying one. Why does No one make 6mm dasher other than laupua?



I think you could sell a bunch of it

Lapua doesn’t make Dasher brass. They make 6BR brass that we all blow out to Dasher. As to why they don’t make it? Eh, no idea, but I expect they have ran the market research to know what brass they can sell at their target margin, and the cost it takes to produce said, and decided it doesn’t pencil out in their favor.

Norma does make Dasher brass, but of a different dimensional spec than what most of us use for Dasher reamers.

A few outlets do hydroform brass for the Dasher, Hunt’s being a very popular one. The downside, they cost the same $1/each plus 55¢/each for the hydroforming service, so most of us don’t end up using them.

Why?

Maybe because "firefoming" 6MM Dasher from 6MM BR is as simple as it gets when making one caliber from another, so folks don't really mind it much, and the market isn't enough so they would make up the start up cost soon enough to suit them.

Dunno though. I am brand new to 6MM Dasher myself.

When making 6PPC for a tight necked (.262) chamber I had to take Lapua .220 Russian brass, neck turn it, and then fireform it. Still wasn't bad.

I expect the answer has to do with economics. If there was enough demand for it they would make it.

I have a buddy that uses a dasher for prs. He didn't want to fireform, so he picked up the norma dasher brass. He miced it and found the only difference between it and lapua is neck length. He trimmed the to length and done... he is charging them with the same load as lapua dasher left behind at matches. The norma brass is good to go after a neck trim.

It will be interesting to see how the Wilson bushing style sizer I ordered matches up with the fire formed brass. If it doesn't match up well, there are folks who will make one that does. Harrell's is one, don't remember the other. I also ordered a Wilson hand seater to use with my arbor press.

But a steady hold and good wind reading will be way more important than the reloading process.

"firefoming" 6MM Dasher from 6MM BR is as simple as it gets

It might be a bit more complicated than that. There’s a false shoulder forming step that must be done before fire forming.

Not an overly complicated process but one of the reasons people offer a hydroforming service as an alternative.

Some also say you can skip the false shoulder steps if you can generate enough neck tension and really jam the round into the rifling so the case head is pushed into the bolt face.

Walkalong where did you get that ammo Box?

Some prefer false shoulders, some prefer jamming, others prefer hydroforming. I tend to prefer a false shoulder, I just run a 25cal expander, then neck down just far enough to close my bolt with tight feel, and then the 6mm expander. I set up the 3 dies on a turret press and crank through new brass pretty quickly. Once they’re formed, I just pull the first expander out of the turret and the sizer and expander are good to go.

Jamming tends to give a cleaner finished product and works the brass less. But for me, it means I end up shooting rounds - aka barrel life - I wouldn't necessarily have had to shoot. False shoulder rounds make dandy fodder for smaller 1 day matches, and if I have to cycle one out, I can, without sticking a bullet in the barrel and dumping powder into my action. So for me, false shoulders fit into my world better than jamming. If I were benchresting with a 6 Dasher (which I wouldn’t do, I’d just go straight up 6 BR or BRA and be merry), then I’d go back to jamming, as I jammed almost everything for BR anyway.

I do not remember, someone who shot Benchrest made and sold them. I had been using a home made one I made with a drill press. Many years ago now. 1993ish.

Thank you walkalong for the info

I've never had a Dasher but my Son shot one for a few years. He though he got better results with the false shoulder vs jamming. I don't think he messed with the hydro method. He was involved in some of the discussion on that accurateshooter thread that you linked.

Its an interesting round.
