Bill,
Welcome, I also am fairly new here. I also agree it is amazing the knowledge and experience that is on this Forum. I have learned a lot about building Longrifles from these guys. I don't know if you are new to muzzle loading also but if you ever get the chance attend Dixon's Gun Making Fair. That will really hook you. Enjoy and ask lots of questions, I will learn from them also. I know there is at least one Rocket Scientist and I'm pretty sure a couple of Brain Surgeons they are great guys and are always helpful. Good Luck,
Bob
