Well I guess for now I'll try edging velocity up and I like the idea of adding a lead weight temporarily to see it's affect. Will try some lighter store bought slugs for a quick check on lighter weight slugs. Thank for all the imput fellas it keeps a guy from jumping the gun when there may be a simple solution. If I have to regulate the hard way it can be done. I'm a good welder and developing machinist. Our local gunsmith gives me full access to his shop at no charge and is always just across the table when I get stuck. I think he just likes helping me out because I keep coming up with projects that keep him on his toes. No simple rebarrels with me.
