No. 10 for Rimless cartridges  1900 - 1940
First Version, Swinging Hook 1900 - 1936
32 Colts Auto
Two "hook" versions - one for reloaders using jacketed bullets, the other for those using cast bullets.
This is a good example of Ideal going the extra mile in responding to customer requests.

The next three photos show a very nice, and very scarce, No. 10 tool in 30-45 G caliber (the 30-03 Springfield)
and accessories.  (All courtesy M. Vasseur.)  The "30-45" is a holdover from the black powder days when the
caliber and powder capacity was stamped.  In this case the charge was 45 grains of smokeless powder.  This
designation was soon dropped for the new smokeless cartridges like the 22 Savage Hi-Power, 250-3000, etc.  
Note the box is a Marlin issue with an Ideal tool. - a common occurrence as Marlin used up the old tools.
A rare large frame in 300 H&H Magnum
I didn't even know this version existed.  Advertised and bought
as a large frame No. 3, and discovered it took a swinging hook.  
Not only that, but it takes the large dies.

This is the only large frame No. 10 I have seen, but maybe there's
one for the 375 H&H out there as well. (see update below)

Note there is no bullet sizing station, even though there's room
for one.  Also note the "12" on the lower handle.  Put probably
an inspector's mark..
A very descriptive sheet showing many of the early, pre-spitzer rimless cartridges loaded with
the No. 10.  This would have been a good companion piece to the above pre-30-06 tool.
As we speak - this rarity, both in calibers and size, showed up on eBay on 1/20/2016.

An interesting tool, but it would play Hell trying to get the dies, which I suspect are the large
version, let alone the decapping tool or the swinging hook.  (I made one for the above
300 H&H by opening up one for the 30-06.)

This one also lacked the sizing station.

A note from the new owner raised the question of the "DX" marking, shown on the right,
and wondered what it signified.  I have had a couple of tools so marked, one a No. 4 with a
detachable mould, indicating the marking was fairly late in the game - I'm guessing the late
'30s to WWII.

I'm thinking it was some years ago that this marking was discussed at length on a gun
message board with the consensus being that it was an inspector's mark.  Any other ideas,  
etc. are welcome and will be posted here.
375 H&H Magnum or 30 Newton
Another Large Frame in 375 Magnum (They must be hatching).  This one is mis-stamped.
A probable "Bad Hair Day" in the
stamping department, or, they couldn't
find an "M" and used a "W" - but forgot
to invert it.

No sizing station on this one, as well,
which implies the large frames were
never intended to have one.  

It would be neat to find the variation that
A probable pre- or post-war modification.
This from the owner: "The tool shows grind marks around the hinge - very neatly done and fully
plated over - that suggest it might  have started life as a No. 6 (with mould) and been factory converted
to a No. 10 shortly after the Remington M1908 and its rimless copies of the Winchester 1894 cartridges
was introduced."

An Unusual 25 Remington
Missing the hook and the decapping tool, but otherwise a nice boxed set with tool and dies retaining all
their original finish.  What make this one a bit unusual is that it has no bullet-sizing station usually seen
on these models.  See above comment on the two variations,
with the "two holer" so far seen only in the

The "Made in U.S.A" indicates a late issue, again somewhat unusual as by then Ideal had switched over
to the "sliding latch" version.  At first I thought
that was the case here with the latch removed, but there
is no screw hole for the latch.
