welcome, we're always happy to hear from new folks. and when it comes to your question, you would be surprised at how many simple questions like that turn out to have rather complicated answers, how many times there are more than one correct way to answer it depending on the situation. most of all when you're not really sure, ask and then ponder your new found wealth of information. I'm going thru that with black powder substitutes, they are all different and sort of the same, and real dam confusing, but I don't really want to blow up a perfectly fine handgun..
