Hello all.

Yes, I like old, obsolete caliber.
A bit obsolete myself...
But, the fact is, that a lot of the good old calibers, pre WWII, where absolutely great, at there time and even so today. Sadly so many has to make a "new and modern" 9.3*62 or 375 H&H....
Ups, that is not what these post is about..Sorry Bact to my question.

The 7x75 R S.E. vom Hofe, a old caliber that has gone more or less in the dark corner, not much information to find about it.

What I find is, not sure if it is right, a 7 mm caliber made pre WWII, delivering power close to the modern day 7mm RM.

If so, why is it "gone"?

Norway, I'm right there with you. newest cartridge I've hunted with this year is 6.5 X 54 Mannlicher/Schoenauer.

I don't see a 7 X 75 Vom Hofe listed in Barnes but there is a 7 X 73 which I suspect is the same cartridge. Is the one your talking about a belted case? The X73 is belted which is quite unusual for a German cartridge. The ballistics Barnes list is a 170 gr. bullet at 3290 fps with 4120 fpe. I'd say that's screaming. Barnes thinks the velocities were taken in a 30 inch barrel which kind of makes sense. It was introduced in 1931 according to Barnes.

You are so right it is painful to think about when you say so many great cartridges were developed before WWII. I would stretch that back to before WWI. If they had the powders back then we have now, and the steels, nothing made today would be one bit better. Most aren't enough better to make much difference anyway. I could easily list a dozen or more off the top of my head.

Thank you.
Good to know I am not alone

No, the cartridges I am talking about is a R one, for break open/falling block guns, it was also a *66 for bolt action guns.

Ahhh...ok. I'll dig a little deeper in my references and see if anything rears its head.

The 7x75R vom Hofe is not a old pre WW II -cartridge. The 7x75R v.H. was developped by Walter Gehmann in the year 1958.

Ah, oh. Ok.
Thank you for the information.
Then my information is not right.

But, do you have any information on the caliber?

From Dixons "European sporting cartridges" pg166
Effectively the last of the Vom Hofe designs, this one based on the 9.3x74R case type. Originally conceived c1939, only one trial lot was produced initially (DWM case #605). Gehmann later modified and introduced this calibre commercially after the other Vom Hofe calibres in 1958, manufactured by IWK (cases #616 & #616A). Apart from prototypes (see below), all known examples of this calibre have the GEHMANN hs including the manufacture by Norma after IWK (DWM) went out of production. German manufacturer Wolfgang Remy is also believed to have made this calibre in the 90s.

Thank you for the information.
Great
Well, it sure was a "hot" caliber back in 1939.

Walter Gehmann who resurrected and kept alive the Vom Hofe cartridges died back in 2012. His business still operates with his son in charge and has a website, seemingly now just focuses on producing specialised competition shooting equipment and accessories.

I visited Walter in his Stuttgart workshop (he had two) back in the eighties, he was busy hot bluing a firearm using a well worn gas heated tank with an old tin hanging in the end containing his blue mix. My German friend was having some gunsmithing work done by Walter so I had a good look around his workshop while they conversed.

My Krieghoff Ulm Primus combination gun has a 7X75R SE vom Hofe as the rifle caliber. I have added a set of double rifle barrels in 9.3X74R and a full length insert barrel in 6X52R Bretschneider and plan to take it deer hunting later this week. So far this season I have accounted for two does, one with an 8X64S Brno ZG47 and the other with a 6.5X57 on a small ring Mauser action. Both were very effective, dropping the animal in question in its tracks, but the 8mm cartridge was fairly destructive and probably too much gun.

I form cases for the 7X75 SE vom Hofe from 9.3X74R brass, using a set of CH4D forming dies. I use a set of RCBS .30-30 to .219 Zipper forming dies to create cases for the 6X52R, which is essentially the 5.6X52R (.22 Savage High Power) case necked up to accept 6mm bullets. I expect to use that cartridge for close shots and the 7X75R SE for longer ones.

Thank you for the reply.

Oh, very interesting to hear how the *75R will do.
What bullets do you load it with? FPS?

Cool stuff xausa!
