Depends on about ten gazillion things -
1. What is the actual bore diameter of your gun?
2. What results did you get with what you shot?
3. How often you wipe out the bore.
4. What patching material did you use and what lube, if any?
5. Whether or not you are going to cast your own.........at about a tenth of the cost of buying store-made.
and more......
