Jarmann-geværet ble approbert
H.K.H. Kronprinsen bestemte at Jarmann-geværet med fast magasin skulle antas for bruk i det norske infanteriet. Det skulle derimot gå lang tid før modellgeværene ble approbert, dette skjedde ikke før 8. april 1884.
Jarmanns gevær var opprinnelig et enkeltskuddsgevær, og dette geværet ble utlevert til tropper for utprøving allerede fra 1878. Modellbetegnelsene som vanligvis blir brukt kan virke noe forvirrende. Jarmanngeværet med fast rørmagasin under forskjeftet ble egentlig approbert i 1881, men det var først med en approbasjon i 1884 at det formelle grunnlaget for geværets modellbetegnelse ble lagt. Den første modellen kalles derfor M/1884. M/1884 ble forbedret av en approbasjon i 1887 der ca. 15 mindre endringer ble gjort på geværet, og det kan derfor være grunnlag for en M/1887. Andre mindre endringer ble approbert i 1888, 1889 og 1890.
Geværet kan brukes både som enkeltskudds- og repetergevær. Bruksmåten kan reguleres ved hjelp av en omstiller på låskassens venstre side. Flerskuddsmekanismen fungerer på følgende måte: en spiralfjær sørger for å dytte patronene bakover i rørmagasinet. Når sluttstykket føres i bakre stilling trekkes den skutte patronen ut av kammeret og kastes ut. På samme tid senkes patronheisen, og en ny patron presses ut på heisen. Når sluttstykket føres fremover heises patronen opp og når støtbunnen treffer patronen i bakkant føres patronen inn i kammeret.

It has long been an established fact that so called multiple discharges or chainfires in percussion revolvers originates from the chamber mouth of the cylinder. But, is this a myth, or are there other explanations? This article seeks to prove that multiple discharges may just as well be caused by loose fitting caps.

Getting Ready for Shooting
Discuss this Project in the Forum
It's about time to start up a new project page. The "Longrifle Project" has not been updated much the past few years, mainly because the rifle shoots very well and I have found the proper loads for her. It's time for something completely new! My new challenge is an original Enfield two-band rifle musket .577 calibre. The proper model designation is "Pattern 1856 Army Short Rifle" (also called "Sergeant's Rifle"), and it's made in 1858. Well, it's about to get started. First some background information.

You can learn more about the history and use of British and American rifle muskets and the Pritchett and Minié balls in the brand new book From Musket to Metallic Cartridge: A Practical History of Black Powder Firearms.
My rifle bears the marks of the British government, but is marked "TOWER" and 1858 on the lock plate. That means it wasn't made at the Royal Small Arms Factory at Enfield Lock but by some of the civilian contractors that made rifles for the Government. It has the following markings that can tell about the origin:
- Lock (inside): W. Corbett
- Barrel (underside): J. Turner & Sons
- Stock (barrel channel): T. Turner, A. Davis and Cooper & Goodman
Otherwise it has Birmingham proof marks and the "broad arrow" markings that make it a service rifle with Government ownership. The proof marks seem to have been defaced on being sold out of the service and then commercially re-proofed at the Birmingham Proof House. On the right side of the stock there is also a very faint W. D. mark which stands for "War Department".
On the butt plate tang the musket is marked:LI
According to the experts this can either mean that it was issued to the Linlithgow Volunteers or Milita, or the 51st Regiment. This particular marking is a bit strange, and the experts can't seem to figure it out properly. E-mail me if you know what it is!
A useful test to check whether your rifle musket will be a shooter is to remove the barrel bands and tighten the tang screw with the barrel in the stock. If the stock lifts up while you tighten the screw it is a bad sign. If it stays in the stock, well, then you have a good chance of getting your musket to shoot.
11.26.04: The P-56 is ready for the first test shots on the target. Since the rifling twist is incredibly slow for a 33" barrel it means it will have trouble stabilizing the heavier and long minié bullets. It is not a coincidence that when the P-56 was replaced by a new model Short Rifle in 1860 the twist was the P-58 Naval Rifle's 1 in 48" and it also had five grooves and a heavier barrel.
I tried the semi wadcutter first, and my expectations weren't high as this bullet is a bit touchy in progressive depth bores. I used my favourite 1861 Armi Sport Springfield replica load: 58 grains of Wano FFg and put up the target at 55 yards.
09.11.05: The best load so far has been as follows: 70 grains Wano PP, Lyman Old Style cast of pure lead weighing 491 grains lubricated with a bee's wax, coconut fat and olive oil mix. The bullet is dip lubed and sized to .5775".
One thing that's smart is to write a journal when you train. Here is a sample of my journal from this summers training.
