January 16, 2010. Winter is raging in IL. Had to change the powder I use in my 300 RSAUM. Since the temp fell below 20 degrees I started losing 135 FPS. Changed over to Reloader 17 and all is good, no matter how cold it gets. I may start writing again if people start reading my materials. Email me if you like my work.. and you may be the motivation I need to start writing again.. all the best... DJ
