Reform 22/250 brass to 250 Savage?
Cal
problems is a brass supply. Midway offers 100 W-W cases for $32 plus
shipping. I can pick up 100 W-W 22/250 cases locally for ten dollars less,
plus no shipping charges. Can 22/250 brass be reliably formed into 250
Savage?
On the surface, it looks as thought it should
22/250 250 savage
Case length 1.92 1.92
length to shoulder 1.5148 1.118
length to neck 1.6636 1.6377
shoulder angle 28 deg 26 deg, 30 min
Looks to me the only glitch would be th shoulder angle and whether it would
iron out ok. Everything else should get pushed back, then trim to length
and Badabing, BadaBoom. Any other monkeywrenches you can see? The new
Speer manual suggests using 308 or 257 roberts brass- that sounds like a
tremendous pain in the a**. Why can't 22/250 be used?
Hey-if I am being stoopid, tell me OK? I just want to save some dough.

case-necks out to take the .257-diam. bullet, which means they will be a bit
thinner than 'real' .250 Savage brass: the issues are how uniformly they
re-shape (thinner on one side or the other, meaning the bullet starts off
out of line with the bore), and how much you work-harden the brass, which in
turn means how long before you start getting neck-cracks.
The second issue is case capacity: since the 22-250 is a high-pressure
cartridge, and the .250 Savage (factory loading) isn't, the 22-250 cases may
well be of heavier construction, meaning less case capacity, meaning
higher-pressures from loads that would otherwise be acceptable.
To save $10? If you keep your pressures reasonable, you could be expected to
get 10 reloadings from those cases. That's one whole buck per hundred
rounds, versus the other problems you could be experiencing.
To put it in a personal perspective: I recently acquired a rifle in Swiss
7.5x55 caliber. Two choices to get brass: re-form .284 Winchester (currently
available for $38/100), or buy Norma 7.5x55 brass for a whopping $65/100. I
have to count the dollars I spend on my hobby more than most of the people
on this forum; I didn't hesitate for a minute before ordering the Norma
brass, because I know it will work, and it will last.

Old Ammo has 250 Savage cases for about 20 bucks a hundred. This is
higher than reforming from something else but it's worth something to
not have to do that.
I bet other places have them too. A lot of obsolete ammo is back. I
don't know what Old West Scrounger wants for loaded ammo. I just paid
35 bucks for 20 32-40's for an old man with a 1894 Winchester his Dad
bought new in the late 1800's.

3000 Savage is the parent case!

Just an opinion of course.
from someone
who was there when you made 22-250 from 250 -3000 brass.
Not that long ago!

#The one iimportant part is the second half of the name . . . 250 . . . 250 -

The one important part is the headspacing datum line on each case.
Since the shoulder angles on the two cases are different, the datum
dimension is almost certainly different as well. The reformed cases
may have excess headspace, or insufficient headspace ( albeit probably
minor ).
Forming .22-250 from .250 cases is different, and depending on the
headspace differences could be safe when the otther practice is
dangerous. In reality I doubt that there is much risk at all in this
instance, but the job is different than necking up a .243 to .260; in
that instance, the case headspace datums are identical. Again, they
likely are not identical between the .22-250 and the .250-3000, and
care should be exercised.

I did} the surplus stuff is plentiful and cheap. It requires a bit more work
trimming and turning the necks, but the heavy mil.spec. cases last a long
time.
