HUBERTUS by Imman Meffert

Dear friends!!
I want to share with you my joy.
After one year of negotiations and 1700 kilometers in one way, I became the happy owner of this gun.
It has two set of barrels - 20 gauge with chamber 70 mm and rifle barrels. All barrels are in good condition.
One hammer is not original.DSC_0984.jpgDSC_0987.jpgDSC_0988.jpgDSC_0989.jpg

I think it has monogram of first owner and compasDSC_0996.jpg

I have some question and wish to listen your opinion
When it was made?
Is it possible to know who was first owner?
What is caliber and cartridge of rifle barrels?
later, i'll do bullet from plumbum.

The seller gave me two cartridge cases as bonus and metal shells for smooth bored barells.DSC_1009.jpgDSC_1010.jpgDSC_1011.jpgDSC_1012.jpgDSC_1013.jpg

Do you have any ideas - for what is inner pocket of this cartridge belt?

To start off, I have to admit I have a fondness for Mefferts and may not be exactly neutral. The gun was made between 1893 and 1912, as evidenced by the use "gauge" measurement to show the bore(not groove or bullet) diameter. In this case, the bore diameter is shown as 67,49 gauge, which equals about 10.41mm( .409+"). To determine the nominal caliber may be a difficult undertaking. Additional information will be necessary to determine the cartridge it was intended for. Most of this information can be determined by taking measurements from a chambercast, and from "slugging" the barrels. In your case, you have the ability to find the diameter and weight of the bullet intended. Here in the US, it is unusual to have an original "bullet mold" ( English for "the device to make bullets"). Especially for black powder rifles, it was common to use bullets smaller than the groove diameter of the barrel, so it is often not possible to find this from measurements of the rifle only. The photos didn't show either the proof load or service load. The service load shown in the tables would have been 5.5 grams of powder and 26.6 grams "shot", for a rifle with 67/49 ga.bore. The powder used in the proof and, by extension, the service load was "Neues Gewehr-Pulver Modell 71". An entirely different powder type/weight and bullet weight could have been( and likely was)used in the actual ammunition for the actual cartridge intended for use. The Cartridge could be based on either the "Mauser Base" case, or the "LK" case. My uneducated guess is one based on the "LK" case. If you can make, or have made, a chambercast, slug the bore, and cast a bullet; I'm pretty sure we can find the nominal caliber, as well as find which case to use. I hope you find this useable.

MARAT,
It seems you made your last two posts, while I was writing mine. Since you have two cartridges for the rifle, a chambercast should not be necessary. It would be very helpful if you would post photos of the cartridge and provide the diameter at the head, at the neck, at the rim, the thickness of the rim, and the length of the case. It would still be helpful if you "slug" the barrel, and cast a few bullets.From what I could see in the photo you did post, both "lubricated" and paperpatched bullets were used.

Mike,
I post few pictures of cartridge and bullet.
the bullet from cartridge is smaller than then from bullet mold.
but both of them are more than 11 mm.DSC_1003.jpgDSC_1004.jpgDSC_1005.jpgDSC_1006.jpg

This cartridge was presented by my older friend.

Mike,
The diameter bullet from cartridge has 11,17 mm
the diameter bullet from bullet mold is 11,56 mm.
Tomorrow, i'll give you exact sizes.
