Modell 1867 Remington rolling block made at Kongsberg Våpenfabrikk (Kongsberg Armoury).
The 12 Remington was adopted by the Norwegian Army in 1867, and it was the the first metallic cartridge weapon in our military history. The calibre was 12,17 mm or .479" and the length of the case was first 42 mm, but was later lengthened to 44 mm. The official military name of the cartridge is 12 mm Remington. When the Remingtons were sold to civilians they where most often converted to fire centrefire cartridges. The advantage with centrefire cartridges was that the shooter could reload the case numerous times.

Loading the cartridges
The first thing to do is to find all the things you need to reload a 12 mm Remington cartridge.
- Brass cases
- Bullet lube
- Black powder
- Caps (magnum caps seems to work best)
- Some sort of wad, milk carton shillings works great.
- A plate of bees wax.
Step 1: Make sure the gun is in a safe shooting condition.
Step 2: Prime the case. Use a wooden hammer or something like that and tap it gently into the case.
Step 3: Pour a pre measured or weighed charge into the case. The original charge was about 60 grains of 2F black powder. You can start a bit lower on the first shots.
Step 4: Put one or more of the milk carton shillings over the powder. It's important not to have any air between the powder and the bullet. If there is an air gap the gun can blow up! If you're using a small charge you'll have to build up the remaining space with the carton shillings. They also help scarping out fouling in the bore.
Step 6: Put a pre-lubed on top of the charge. Mind the air gap! The original lube was a sheep tallow/bees wax mix, but there are plenty of other bullet lube variations. It doesn't matter if the bullet is loose in the case, you just have to be careful when you're carrying it. The accuracy won't suffer from it. The cartridge is now ready to be fired.
- Remove the caps.
- Wash the cases in soapy water
- Clean the gun and oil it.
