摘要： A method of manufacturing an improved lead-free primed rimfire cartridge for ammunition (12) or industrial powerloads (52) providing a gas source for driving fasteners with power-fastening tools. A lead-free priming mixture (80) is consolidated into an annular cavity (20) of a rimfire casing and dried in the cavity. The primer is secured in the cavity by tamping at least a portion of propellant (30) into the casing against and over the dried primer. The tamping pressure per casing may range from 1,300 psi to 8,800 psi (91.4-618.7Kgf/cm²). Any remaining portion of required propellant (90) is added over the tamped compacted propellant layer. The ammunition and powerload casings are then sealed and finished in a conventional manner. A rimfire cartridge for both ammunition and industrial powerload applications manufactured as described above is also provided.

摘要翻译： 一种制造用于弹药或工业动力负载的改进的无铅底漆火焰筒的方法，其提供用于用电力紧固工具驱动紧固件的气源。 无铅起动混合物被固结成轮辋燃烧套管的环形空腔并在空腔中干燥。 将底漆通过将至少一部分推进剂通过干燥的底漆和/或干燥的底漆上而被压入套管而固定在空腔中。 每个套管的捣固压力可以在1300psi至8,800psi（91.4-618.7Kgf / cm 2）之间。 任何剩余部分的所需推进剂都加在夯实的压实推进剂层上。 然后将弹药和功率负载外壳以常规方式密封和完成。 还提供了用于如上所述制造的弹药和工业功率负载应用的火焰筒。
