I started reloading in January. My first set of dies was 38 Special/357 Magnum. I learned a lot and tried several recipes before I was satisfied. I now have sucessfully reloaded .45 ACP, 9mm Makarov, 357 Sig and .44 Magnum. I intend to get .40 S&W, 9mm Lugar and .45 Colt dies before I start to reload for my rifles. I do not know if the loads that I have produced so far are the optimum since I do not own a chronograph. That said, I am reloading with the goal of creating rounds that I can plink at the range with with accuracy and comfort. If I were reloading for SD or for hunting I would need to invest more time in the selection of bullets, powders and primers.
As I continue to experiment (following load data) I become more competant. MY shelf of shame where I keep my scrwed-up rounds is quite substantial.
