[QUOTE="Kennibear, post: 914815, member: 51650"] Fluted chambers started being used when the first self-loaders were being adopted by the world's militaries. The early designs lacked primary extraction and the trapped gas between the case and chamber wall helped the case release from the chamber and the anemic extraction of early designs became more reliable. Dirt in the chamber screws it up no matter what. Generous chamber size helps with dirt too. H&K used fluting on their roller locked design because it lacks primary extraction. It is momentum driven and the initial impulse given to the bolt carrier is all she wrote. Gas designs have a longer impulse cycle and have residual force being applied when the primary extraction is going on. Our requirements are quite different and a tight fitting chamber is the end all of it. But there is no doubt that the roller locked self- loader pioneered by the MG-42 is a proven design in implements of war. KB [/QUOTE]
