RE: working up a load?
We have different methods, but the basics are start at the bottom of the load range and go up 10 gr at a time when you find the load that shoots the best try 5 gr either side of it.
After you have the best load try a single fiber wad, then a wad with a greased wad on top of it, then a wad with 20 gr by vol of corn meal on top and a greased wad on top that. The gun will usually have a preference. Lee
