I'm ready to start reloading for my 357 Sig using an RCBS Sizemaster single stage press. After perusing previous threads, I'm a little confused on which dies to use. Seems there are several opinions/combinations people are using. Is it really that darn difficult to reload for? Do I really need to buy a seperate .40 sizing die? Why can't I just buy a set of Dillon, Lee,Hornady, etc.. dies and get to work? If money were no object, what die set/combo would you recommend? My goal is to turn out reloads that are consistent and of good quality with minimal hassle. Also, is AA9 still the powder of choice for the Sig? Seems from what I read, it produces high velocities with safe pressures. In addition, it fills the case to capacity helping reduce bullet setback. Any bullet recommendations would be appreciated too. Thanks in advance.
