Now that you mention it, that seems obvious. I've never seen it put quite like that, but it sure makes sense. Thanks!

I have a 550 that I've used for 9mm and 45acp and am about to buy a caliber conversion for 38 special. In both 9mm and 45acp, I've used a separate crimp die. However, looking at the RCBS die sets, it looks like they seat and crimp in one die. What should I do for 38 special? Is a separate die for crimping important? I know both lee and Dillion have 4-die sets. What is gained by using the fourth die? I can't imagine RCBS would sell a 3-die set if it wasn't able to get the job done.

That's good to hear. Thanks rdinga!

How does WST respond when the temps drop? Living in southcentral Alaska, 70F is a nice summer temp. If I have a load that works well at 70F, what should I expect from it at 20F? 0F? -10F?

Thanks for all the info, I appreciate it!

I'm accostomed to lead for revolver loads and FMJ for semi's. Before coming here I didn't know people shot 9mm bullets without jackets. Is there anything a shooter needs to consider before starting to load lead in a semi? What feeds well? Any types to avoid?

Thanks for the advice guys. 4 dies it is.

I've read several threads discussing the advantage of using seperate seating and crimping dies. I think I understand the issues, including OAL consistancy and bullet setback. I'm a new reloader and would like to ask for advice for my situation from more experienced reloaders. I have a Dillon RL 550b on the way and have been given a Lee 3-die 9mm die set. It's not a perfect match, but can I use the 3-die set and leave the fourth station empty? If not, can I buy any brand of factory crimp die or do I need to buy a full 4-die set? Or should I instead be thinking of something like the RCBS Lock-Out die for the available station? I appreciate any advice. I'll be loading 9mm with DP 124gr FMJ bullets and seeking a light range load to begin with. As a new reloader, I'm interested in making safe rounds that I can be proud of. Speed and efficiency can come later. Thanks!
