The purpose of these long, heavy wall jackets is to provide bullet makers with a convenient, ready-made source of bullet jackets for .412, .411, .410, .408 and other bullets in the same general diameter, and also to use as a universal starting point for redrawing to make .375, .366 (9.3mm), .358, .348, and .338 rifle bullet jackets. The jackets can be reduced using a JRD-1-S or JRD-1-H draw die (maintaining the same .030 wall thickness), or the jacket walls can be thinned at the same time by using a JRD-2-S or JRD-2-H draw die. Because of the length, the CHP-1 or CSP-2 press is recommended over the CSP-1 for one-pass jacket reduction, especially with jacket wall thinning at the same time.
Lead wire which fits these jackets is available from Corbin in 70,000 grain spools, packaged on a spool for easy feeding. The wire size to use is 0.312-inch diameter, which can be swaged to about .325-.330 to fit into the original jacket diameter for various 40 caliber rifles.
