I'm about to acquire a S&W 340 PD and was looking to start reloading for it. This will be my first revolver and first time reloading for it. I was thinking of loading .38 +P for it and was looking for some recommendations. What types of powders would you want to use for this extremely short barrel? I was thinking of using a Hornady 125 gr. XTP bullet. Thanks for the imput from you seasoned folks.
