Slaget ved Kringen
Slaget ved Kringen var en trefning i 1612 like sør for Otta i Gudbrandsdalen der et norsk oppbud av noen hundre bevæpnede bønder fra Dovre, Lesja, Vågå, Fron og Ringebu overfalt og nærmest utslettet en skotsk avdeling på 300 leiesoldater. Skottene var på gjennomfart til Sverige under det såkalte skottetoget, leietroppenes marsj for å slutte seg til de svenske soldatene i Kalmarkrigen mellom Sverige og Danmark-Norge 1611–1613.

Slaget ved Kringen er et av de mest legendariske militære slagene i Norgeshistorien. Det ble fulgt opp med en massakre i den såkalte skottelåven på Kvam, der mesteparten av de skotske fangene ble drept.

      Multiple Discharges in Percussion Revolvers

    • Multiple Discharges in Percussion Revolvers

      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.

    R&D Conversion Cylinders

    The years following the American Civil War was a time of unrest and upheaval, and a time that saw a transition from the percussion system to metallic cartridges. Percussion revolvers, also known as cap and ball revolvers, were made by the thousands before and during the war, but the principle of muzzleloading started to become obsolete when the new metallic cartridges became common after the war.

    The R&D cylinder.

    The cap and ball revolvers could easily be converted to use the new metallic cartridges. In the 1800s there were many methods for converting percussion revolvers. Some variants even allowed the shooter to use both the old percussion cylinder and a new cartridge cylinder. Many patents were based on the old percussion cylinder, in which a chamber was bored out for the cartridges. At the rear where the percussion nipples are located, it was made some sort of device that facilitated the chambering of the metallic cartridges. The R&D conversion cylinders consist of two parts: a cylinder and a back plate with six individual firing pins. The cylinder must be removed from the revolver to be loaded. In the cylinder I use in my .44 Remington New Army, six cartridges are slipped into the cylinder, and the back plate is placed over the cylinder. There is an indexing pin in the body so that the firing pins align properly with the chambers in the cylinder. The cylinder and back plate is then inserted back into the revolver. This may seem a bit cumbersome, but it is way faster compared to loading a percussion revolver. The percussion revolvers could be loaded with paper cartridges, but they tended to get wet and spoiled by moisture. This problem was as good as eliminated with metallic cartridges.

    The plate with firing pins.

    Today the conversion cylinders for replica cap and ball revolvers have become popular among black powder shooters. The R&D cylinders are available for the most common replica revolvers. The cylinder that I use in my .44 Uberti Remington New Army is in .45 Colt (Long Colt). Another alternative is the Kirst Koverter cylinders. These cylinders only take five cartridges, but they have a loading gate that eliminates the need to remove the cylinder to reload. Kirst Konverter cylinders are somewhat more expensive compared to the R&D cylinders.

    Roundballs are accurate in the R&D cylinder.

    So far the accuracy from the R&D cylinder has been very good, as a matter a fact it seems to shoot just as well as the percussion cylinder. I have had best results with roundballs, but it also performs well with Lee's .456" conical ball which is designed for percussion revolvers. I size the balls to .454". Only top grade, certified steel is used in the production of these cylinders, and the manufacturer states that is possible to use light smokeless loads in the R&D cylinder, but I haven't tried it and I have no intentions of doing it either. In a revolver that is made for black powder I feel it is more appropriate and safe to stick to black powder.

    .45 Colt cartridges, loaded with conical bullets and roundballs.

    The conversion cylinders are allowed in the metallic cartridge competition Smith and Wesson when competing in competitions held by the Norwegian Black Powder Union. Some shooters use the R&D cylinders with very good results. Most shooters load the cartridges with roundballs, and they even grease the cylinder mouths the same way as many cap and ball revolver shooters do. With a R&D cylinder you only need one revolver to shoot both in the Mariette (the percussion revolver competition) and the Smith & Wesson competition.

    Here's a small video of how the R&D cylinder works:
