9x23mm Winchester Full-Power Loads

9x23mm Winchester Full-Power Loads
Warning! Notes: The loads identified as "full-power" were developed for modern guns chambered for the 9x23mm Winchester and should not be fired in guns chambered for any other cartridge. Reduce those powder charges by 10 percent for starting loads. Loads identified as "light target" should be safe to use in guns chambered for the 9x23mm Largo as well, but only if they are tight and in excellent condition and only if Winchester 9x23mm cases are used. Winchester cases and Winchester WSR primers were used in all full-power loads. (Handloader Issue 186)
