Here are the reload recipes from Alliant for the Sport Pistol powder that I will be using. https://www.alliantpowder.com/reloa...wderlist.aspx&type=1&powderid=42&cartridge=23 The Xtreme 115gr plated bullets are not included in the chart. The lowest max charge for 115gr jacketed is 4.7gr. Since plated bullets should be loaded ~.2gr less that jacketed, and it is recommended to start at 10% less than max, I'm thinking that 4.0gr of the SP is a good starting point. Does that make sense or am I totally off here? Thanks.
