Hog Daddy I have 2 questions

1. I have an remington model 788 in .308. There is some rust pits in the barrell. New barrell job cost more than it is worth. Really enjoy the accuracy of this rifle. What would you do?

2. I have a single shot 45-70 govt. and I want to make some hanloads for it. I dont want the flat nose or round nose bullets that are common because of lever action safety. It is a modern chamber and I can exceed the pressures over what is recomended for black powder cartriges. Have you seen any pointed boat tail bullets in .457"? If so do you have any loading info for loads slighly over black powder cartridge pressures. I dont want to test the steel, I just want to be a little faster and more aerodynamic than the factory loads that are universal to old and new firearms.
