Hi
I have just found a guy in southern Germany who manufactures sub-caliber cartridge cases (not adaptors!)

He machines (cnc) from solid brass stock for instance a .222 Rem case with internal dimensions of a .22 Hornet; or a 30.06 with internal dims of a .30 carbine (Reduzierh�lse)
or, for the .22 calibers, a 'Diaboloh�lse' (air rifle pellet with a shotgun primer) which you can use in the garden or for practice purposes.

I have just bought some for the .222Rem barrel insert in my Otto Bock BBF and am having a lot of fun in the garden!

Noise level of an air rifle!

His website is http://www.samereier.de/

Name: Johann Samereier

(I have nothing to do with the business - just thought this might be of interest to some people here on the forum)

I try to add a list of his stuff here:


Kaliber
. 222 Rem
. 223 Rem
5,6 x 50 R
. 243 Win
6,5 x 55
6,5 x 57 (R)
6,5 x 65 R
7 x 57 (R)
7 x 64
7 x 65 R
7,5 x 55
. 30 - 06
. 30 R Blaser
. 300 Win Mag
. 303 Brith.
8 x 57 J(R)S
8 x 68 S
8,15 x 46 R
9,3 x 62
9,3 x 64
9,3 x 74 R
.375 H&H

prices are between Euro 5-6 per cartridge and come in batches of 10

Not sure whether he speaks english; but if necessary, communicate through me, I'd be happy to translate

Regards from England

Whats the subcaliber for the .375?

not sure of the proper term for something like this - never come across it before - so I used the term 'sub-caliber' , although the actual caliber stays the same.
The picture shows the volume to be about half (or even less in the bigger calibers) of a standard cartridge.

What I find interesting is that it allows you to shoot very light loads without the danger of a 'detonation'
Loading data for the different calibers are on his website under 'Reduzierh�lsen' and then 'Ladetabelle und Preise'

Particularly interesting in the .22 calibers -
in my case, I can load and shoot a .222 Rem as a .22 Hornet

also, I like the idea of the other type of cartridge he offers (again, this is .22 calibers only): the 'Diaboloh�lse', where you shoot a .22 air rifle pellet or round ball with just a shotgun primer (see photo)
This basically makes it a 'Tesching', as indoor rounds used to be known in Germany.
I have tried it today in my garden - about 25 meters on an air rifle target - shoots 1" low with the .222 settings on the scope.

I was confused by your terminology, thinking of the old chamber inserts which allowed, for instance, a .32-20 cartridge to be fired in a .30-'06 chamber. Now I realize that what is being sold is something altogether different, a cartridge case with reduced capacity to allow a .32-20 powder charge to be effectively fired in a .30-'06 chamber with no change in performance.

The only drawback I can see is the possible lack of longivity of the turned cases. I wonder how many repetitions of neck sizing they can endure before cracking.

I believe this is a variation on the idea of the "Everlasting" cartridge case used by Schuetzen shooters in the late 1800's

yeah - apologies for the confusion
I couldn't think of a proper term in english for these things.

But your description describes exactly what we have here.

As to longevity of the cases:
the maker recommends as follows:

a) do not use excessive loads to avoid bulging of the cartridge case

b) do not use an expander die on the neck, but neck-size outside only

c) warm up the neck of a cartridge for 5 seconds with a 'soft' gas flame after each 5 shots (without bringing it to a glow)
in order to retain elasticity.

he reckons that the cases will actually last quite a long time (without giving a figure of course...)

I personally would also not put a crimp on the bullet.
I have bought a batch of 10 in .222 Rem - if I start using just one of the cases and try to load this, say, 25 times, I should find out in a few weeks time what state it is in after 25 loads.

Best regards

Hi Gunter,
I have also bought some of them but have yet to get around to loading them, time will tell on the cracking issue.
Whereabouts in Kent are you living? as I have a 2nd home in Dover.

Hi Martin,
small world - hehe

I live in Rochester, Kent
some nice pubs around here -
if you find yourself in the area, give me a shout and we can take refreshment.

I take it you are in Bavaria?

Best regards
G�nter

Hi Gunter,
I lived for 25 years in Deal/Walmer but now primarily in Bavaria with just a holiday home still in Dover = it is a cheap & cheerfull box but it is OK for using as a base for the pigeon shooting permissions whenever I can get over there.
Lol

I have a 5,6x57 RWS. It's a Savage action but built up by Anschuetz. This caliber is a metric that compares to the .220 Swift but with a better twist rate so it takes heavier, (74-grain) better built bullets and is therefore suitable for larger game up to fallow deer size, (where legal). It has 2 adaptor cartridges, which was the norm for this caliber as the case has a special extra thick neck to accept adapters in it's chamber. They're made by Walther, one in .22 Hornet and one in .22 WMR (.22 Magnum). They're not reduction cartridges in the sense that they have a parent case with a reduced internal powder case, rather they're adaptor cases that engulf the smaller case. The .22 Hornet especially is very accurate, despite the apparent mis-match of twist rates. It means I can start off a youngster on targets with the next to no recoil rimfire, graduate to the Hornet on hares and then onto deer as they get older and bolder. My son shot his first deer with it, but he now prefers his Krico .243 although not for any particular reason in terms of extra performance. The 5,6x57 is brilliant on feral goats and would be a perfect roe deer cartridge - if we had any down here in New Zealand.

The reduced hulls sound like a good idea, if used carefully. I just might give them a go.
