Indeed, they are most expensive and you can have your sticks of Brass turned from a single piece of Brass Stock @ Rocky Mountain Cartridge Company @ $122/20 sticks. But a Bit of an UpHill Battle with them as they think they know more about the 6,5X70R and say I have an enlarged chamber so they won't turn the cases until I send a fire-formed Case. Not a Big Deal, but an additional $28 plus whatever shipping costs.

And it is the Cost that makes me Pause & use the Cracked Cases of Others, before I ignite a New Stick of Brass. I have resized & trimmed a few from 74,5mm cases, but that's it. I have quite a supply of 0.366" Cast Lead Bullets w/ Gas Check, but I wonder what I might use had I not had those? I guess a call to Northern Precision Custom Bullets and hence, yet another expense?

But back to RWS & the 6,5X70R Berdan Primer Pocket sticks of Brass, why would they make the Berdan version? Surely it couldn't be cheaper to make a Berdan Case vs a Boxer Case? I wouldn't think Europe reloads too many Berdan Cases?

Should one have the desire to shoot some very expensive ammo, some sites have the 6,5X70R @ $100 / round:

I guess it has a spezial powder or something?????

Most likely a small-scale commercial Waffen-Dorfner load (Austria) with Dieter Horneber cases from the earlier 2000s years.
And most likely a pack of 10.

Raimey,
OK, you more or less answered my questions. I glean from your answers that Bertram likely doesn't anneal and trim their cases to length prior to shipping. There is no way a proper 6.5x70R case could stretch to 74.5mm in the first sizing. When making some of my own cases I depend on the stretching and would be happy with half that much. Bertram cases are expensive enough to buy but your experience with cracks in their new cases means the actual cost for useable cases is much higher. You asked why RWS would sell Berdan primed cases, I don't know if they do, but if so, it would be to use "on hand" production equipment rather than setting up expensive new facilities for a few cases. Your procedure for annealing with the water in a pie plate is pretty much what I was suggesting. You might find it convenient to have one of your boys to tip the cases over while you wield the torch if you are annealing a batch of cases rather than individual ones. Trimming 74.5 mm cases to length by hand takes a lot of time and effort, it would help a lot if you saw most of it off first. I use a horizontal/vertical band saw, but it is hard to get a straight cut. I think a small (3or4") cut off saw from Harbor Freight would be a better choice if you don't need something for general machine shop work (and cheaper too). The $100 per round ammo is collector ammo, not shooting ammo. There is no way a shooter that needs multiple rounds can compete with a collector that needs only one (I'm also a collector and have to be satisfied with a fired case instead of that price). As far as turned cases are concerned, I explored them for some of my other projects and decided against them because the grain structure of turned brass is not as appropriate as drawn brass. The only way it would work at all for my projects was because they were large enough to have very thick walls and 6.5x70R cases would have very little space for powder. As far as the load you found, it seems to be pretty much like the factory load (except with a cast bullet). The other good news is, if the cast bullets (.266") prove unsatisfactory, your larger diameter barrel will take American standard 6.5mm nominal bullets without having to resize them as I have to do with my German barrels. You may need a lighter spitzer bullet to avoid exceeding the length of the original factory bullet, but that would allow a little higher velocity.

He didn't ask that.
He asked why DWM (and possibly, but much less likely RWS) still produced Berdan-primed cartridge cases at a time, when virtually *ALL* European hunting cartridges were still Berdan-primed.

Good grief.
What an astounding *surrrrpriiiiise* !

Now Ford, I haven't cracked any newly formed cases as I am trying to learn on the previous cracked case effort by others.

Raimey,
I misunderstood your previous post; I thought you were checking new Bertram cases for cracks to avoid wasting time on cracked ones. For the life of me I don't understand how the person you got fired cases from could have actually used ammo with 74.5mm long cases. Learning from the mistakes of others (I have made plenty) is the right thing to do, to avoid them yourself.

When Berdan cases were the standard, they were practically the same cost as boxer cases would have been. The savings would be in the primers themselves, in making and placing the anvils, which wouldn't be necessary with Berdan cases.
