OK, I just got off the phone with Lyman, These are not what you are looking for. The mould says slugs that do not require rifling. The customer service guy said they don't have to have rifling, however they are more accurate with it. So perhaps something else. Black Jack Hill offers a .69 minie as well as .69 RBs. I think I will try them first and see how they do. That is all for now. Its time to go load my truck for my turkey trip. We're leaving at 2:30AM to get to the property by 5:00. I hope to post BP turkey pics on 4/1/06. BTW Doug S. has a way to make a rear sight for the Pedersoli without any modifications to the gun itself. Just thought you might want to know.
