How do you all do, this Christmas Santa granted me a set of RCBS dies in .40 S&W/10mm. I'm anxious to get to reloading but I need some advice. I only have 165gr RNFP as far as bullet heads go. But powder. . . this is a bit tricky and where I need data, I have Winchester 231 Ball Powder, Winchester 296, IMR 4064, Alliant Red Dot, Alliant Unique, 700X and 800X powders to choose from. Which, in your opinions, is the best powder to use for 10mm and what is the reloading data for said powders? If you could please give me a source for your data so I can double check it. Not to say I don't trust anyone here but I'd rather be safe than sorry. Thank you guys for any help you can give me.
