WELCOME!!! If you choose pyrodex, one thing to consider with the encore is blowback into the action. I wasn't aware of the problem, and ended up having rust form in my action. with the 209 primer, you get a fair bit of blowback. after you find a load that your happy with, you might want to look at a primer conversion. I switched to the 25acp conversion, and have no blowback into the action at all. food for thought after your done load development. Good luck, and please don't hesitate to ask questions. we're all here to help.
