chuck, since the min to max loads for the 204 is so short i suggest starting at the middle of the loads and working up toward max in tenths of grains of powder. load about 5 of each loads and keep them seperated and marked in a sandwich bag. also mark targets for each load and head for the range. fire these off sandbags without moving the scope and see which load gives the best groups. the load that gives the best group is the one you want to use. good luck with your rifle. also you might want to try different bullets and powders using the same process.
