In the 1920's the danes started refurbishing the Krags as they were pretty much shot out and worn down. The original barrels has a "Metford" rifling and a leade over 1" to accomodate the 227grain round nose bullet of the time (chamber A). Newer stamped on the barrels as noone knew that there would be revisions on chamber design. The replacement barrels has a standard cut rifling and a C chamber with a little over 1/4" leade. Later the leade was lengthned to almost 1 1/4" to accomodate armor piercing and tracer bullets wich was way longer than the original 196gr spitser. Pic 1: Is a black powder loaded round 77grains highly compressed and 7½ grains of priming powder to set it off. A 227grain steel jacketed bullet going a whooping 470m/s~1540fps but generating 2300bar~33.3kpsi of pressure. And the "Metford" rifling used in the first barrels. Pic 2: shows the marks stamped on the action just ahead of the bolt. Top mark is a standard C chamber of little over 1/4" and the bottom one is for the long throat. |
