Hey guys. I have been reloading .357 and .44 for a few years and plan to start loading .40 S&W. However, I have some questions: 1) When I started looking at dies I got confused. My current dies are Lee and I would like to stick with those. However, I see 3-die and 4-die sets out there. I know the 4th die is a crimp die but for a plinking load do I need that die, or are the 3-die sets made for people who want a particular crimp? Revolver sets are 3-die sets and end with the seating die. I don't mind spending the extra money for the 4-die set if there is an advantage. Also, if you can tell me good sources for dies that would be great - MidwayUSA has everything on backorder it seems. 2) I see die sets for .40S&W and for .40S&W/10mm. Is there any advantage to the die set that only does .40 S&W? 3) What primer size does the .40 S&W use? Is it the same as either the .357 or .44? (admittedly I could look this up but while I'm asking the other questions...) 4) Any additional case prep tools I will need? Right now I have a deburring tool and a primer pocket cleaning tool and that's it. 5) Any good plinking loads for the .40 S&W in a Glock 22? 6) How many reloads can I expect standard brass cases to last in .40? I usually don't worry about this in the revolvers but both of them are pretty sturdily built. Thanks in advance. EDIT TO ADD: I will be doing this on an RCBS SB5 single-stage press (the one that looks like the Lee O-frame).
