We get a lot of new shooters here asking for information on loading the C 9 and other 9mm's. While nearly any medium fast powder CAN work, some are more popular than others. I shoot self-cast 125 grn lead bullets sized to .358 in both my 9mms and .38 Specials. I also use CCI 500 or WSP primers (Winchester Small Pistol.) Two of my favorite loads are 4.7 of True Blue (Ramshot) with an COL (cartridge overall length) of 1.05 and 5.0 grns of Green Dot (Alliant) with a COL of 1.05 THIS IS SAFE IN MY GUNS AND MY GUNS ONLY! Start both loads [email protected] grns and work up 0.1 grn at a time. For those of you just starting, other tried and true powders are Unique, Bullseye (Alliant), Competition and Zip (Ramshot), And both #2 and #5 (Accurate). Manuals are available from most powder and bullet manfacturers on line. Here's a short list to get you started: http://www.alliantpowder.com/ https://www.hodgdon.com/ (Hodgdon, IMR and Winchester) http://www.ramshot.com/ (Ramshot and Accurate) http://web.archive.org/web/20071209210541/http://www.stevespages.com/page8.htm (Now maintained by one of our members) As this is for beginners, one more piece of advice. Like others here, I've been doing this for over 40 years and I MAKE MISTAKES. Read an manual - better yet, read two or three. Not just the data charts, but the articles and information. Double check everything, especially your charges. Have only ONE powder at a time on your bench. Use reliable data from reliable sources that you trust . Some guy with the handle "Planet Smasher" ain't it! Hope this helps. Be happy to help the noobs in any way I can - we all had to start somewhere. Stay Safe.
